Summary:
200+ refugees from Vulcan's sister planet T'Khut have been living for weeks in the 350 year old Earth Cargo Service vessel Zirkiv, in orbit of Cor Caroli IX. A shortage of topaline, needed to build atmospheric domes, is preventing new domes from being built, so a treaty is signed to expedite mining more on Capella IV.
Rebecca Greenblatt of the Janus Mining Corporation is assigned to upgrade the mining facilities on Capella IV. The technology is 100+ years old and their economy about to collapse; the Capellans refuse to let the Federation return to the planet for maintenance after the teer, Leonard Akaar, was overthrown and exiled by a group called the toora Maab.
The refinery is just about operational when a Capellan named Kuun insists that Rebecca show him how it works; however, en route, the refinery explodes. Scans reveal traces of Cabrodine, a common element used in explosives, leading them to suspect sabotage.
Sonek Pran, a former aide who was dismissed when President Zife resigned, is back to being a professor on Mars, but wishes he could help more directly with the current crisis. Serendipitously, he receives a call from the Palais de la Concorde asking him to a seemingly urgent meeting with the president's chief of staff, Esperanza Piniero, which he accepts.
Cestus III has become a refugee center, since it was spared from the Borg invasion. An Andorian ship, the Kovlessa, was turned away from Zalda. Governor Gari tells them they'll house them in a baseball staidum.
Sonkek Pran arrives at the Palais de la Concorde and meets with Piniero, who says Bacco is again requesting his services; he accepts. While the Federation recognizes Donatra's government, they're providing aid to Romulus, which refuses to trade with the Star Empire. The Aventine will take Pran to Achernar Prime to speak with Empress Donatra, which he is quite happy to do.
President Bacco attends the Federation Council session addressing Zalda turning away the Kovlessa. After hearing the play-back between the ship and Orbital Control, the Zaldan Councillor says they will not be part of a Federation of liars--lying being completly intolerable to the Zaldans--and exits the chamber. Zalda is stricken from the refugee list until the reason for refusal can be determined.
Ty'Gokor is serving as the temporary capital of the Klingon Empire until the First City is rebuilt; Martok may make it the permanent chair.
Martok's son, Captain Drex of the I.K.S. Rovlaq, patrols near the planet Krios, protecting the Mempa refugees from potential Kinshaya attacks. The Kinshaya, a small nation that have been at war with the Klingons for centuries, recently conquered the Kreel, adding their fleet to the Kinshaya's own.
A fleet of 12 Kinshaya ships attack, upgraded with Breen disruptors and enhanced Romulan shields. They destroy many of the convoy ships, as well as Governor Doq's satellite, before the Rovlaq can stop them. Ultimately, the Rovlaq is also destroyed by the overwhelming numbers.
Dax and Bowers welcome Pran onto the Aventine; Pran can immediately tell Bowers doesn't want him there. Later that night, Pran plays his banjo for the crew, and they are enamored.
Riots break out in New Samarkand on Alpha Centauri over medication; Starfleet is called in to help.
The SCE ship USS Musgrave is ordered to Maxia Zeta IV, where a new dilithium mine has been opened up. However, this released farantine into the atmosphere, which stops electronics from functioning. The SCE team previously devised a paint that somewhat negates these effects, but removing it from the atmosphere will be significantly more complicated.
Pran, Altoss, his assigned security, Bowers, and Keddair take a runabout to Artaleirh to deliver food. The Romulans there are all emaciated, but tell them to leave regardless, saying the services of the Federation are no longer required. Sonek convinces them to take the food, since it's already there, and they accept. Back on the runabout, Sonek says it's more than pride that's stopping them from accepting the charity.
Back on the ship, Pran checks FNS news, which reports that the explosion on Capella IV was caused by the toora Maab, who haven't been active for 100 years. He can't help by draw a line between these disparate factions refusing Federation help for seemingly no reason.
Sonek meets with Empress Donatra. He says she's already beaten Tal'Aura; she told Bacco and Martok about Donatra's plans to form the Imperial Romulan State weeks before she announced it, knowing she couldn't do anything about it. Donatra has superior forces and the support of the people, so she just has to wait it out; but the people will suffer the most this way. He says if she offers to trade with Tal'Aura, the Romulan Empire will know who fed them, and the Federation will be on her side. She agrees to consider his proposal.
The next day, Donatra asks for a tour of the Aventine. She tells Dax she wants to open a trade dialogue with Praetor Tal'Aura, but wants Dax to open the negotiations, to which she agrees. Tal'Aura refuses to any negotiations between the Federation or Donatra, and says any aid agreements are terminated. Pran says nothing they could've said would've made a difference, because Tal'Aura knows something they don't.
Archbishop Retej, leader of the Seventh Holy Kinshaya Attack Fleet, takes his ship to conquer H'atoria, a world on the Klingon/Federation border. Upon arrival, they find it devastated by the Borg, but its location is more valuable than its resources.
Kalavak, the Romulan Star Empire's ambassador to the Federation, shows up at Bacco's office to tell her that the Empire will no longer take aid from the Federation, and no Federation ships will be allowed to enter their space without permission.
After the Romulan ambassador leaves, Bacco meets with Akaar to discuss the situation on Capella. There is replacement equipment on Starbase 10, they just need a ship to pick up and deliver it. Just then, Dax reports in on Pran's lack of success, so Akaar orders the Aventine to deliver the equipment to Capella.
Afterwards, Bacco meets with Klingon Ambassador K'mtok, who first asks about the topaline delay, then asks for Starfleet support against the Kinshaya attacks on H'atoria and Krios, where Martok's son was killed. Akaar says the earliest they can send ships is in 2 weeks, and K'mtok says the Klingons will remember this day.
Commander Bojan Hadzic of the Musgrave reviews the scans of Maxia Zeta III and finds there's no farantine on it; Maxia Zeta IV is a sister planet to III, so if there's none there, it must have been placed there as sabotage. They need a sample of the faranite to test it, but can't beam back from the planet once they beam down. They decide to outfit a shuttle with chemical thrusters to break out of the atmosphere.
The SCE is secretly working on Project Reassimilation: collecting salvaged Borg technology to try and reverse engineer it. However, since it's all inert, no progress has been made.
Pran starts piecing together the disparate attacks and disasters that have happened over the last few weeks, and sees a pattern emerging wherein the trade and shipping routes between the Federation and the Klingons are being cut off. He does a search for farantine and finds an article about a Ferengi named Sekki who was caught selling artificial faranite to a group called the Matter of Everything. He asks to speak with Dax right away.
Martok orders Klag to take 5 ships and recapture Krios; the other dozen ships in the fleet will guard the convoy to Mempa.
Pran asks Dax for runabout to take to Zalda; he believes the Ferengi woman, Sekki, is part of a conspiracy to drive a wedge between the Klingons and the Federation, and Zalda is the key--though he's not sure why. He says when Bacco asked Ferengi Ambassador Derro to hire the Breen as mercenaries against the Borg, he also tried to sell them weapons; however, he was outbid by Sekki, who upsold them better weapons--the same ones used by the Kinshaya. Sekki was arrested for selling artifical farantine, which was used on Maxia Zeta IV. Dax doesn't really buy it, but says they need Zalda back anyway, so she agrees.
The runabout arrives at Zalda and Pran requests a meeting with Councillor Molmaan; he's told he's unwelcome and to leave. He says if they turn him away, they're practically declaring war on the Federation, and Molmaan answers. He says Pran is lying because the Federation wouldn't attack a planet housing its own refugees; Pran is surprised to learn they do have refugees there. Pran explains that someone is lying to intentionally divide Zalda and the Federation, and that Molmaan needs to go back to Earth and actually talk to the president this time. Molmaan agrees, and says that no refugees in need will ever be turned away.
Pran contacts the president and gives her the good news; she's at a loss for words. Akaar says he'll start diverting refugees to Zalda right away. Afterwards, Pran tells Altoss and Trabka to take him to Maxia Zeta now that he's sure there's a conspiracy going on, despite their orders to go to Capella.
Aventine arrives at Capella, but Dax has decided that Pran's theory may hold water, so she tells Rebecca Greenblatt that she won't hand over the replacement equipment until Security Chief Kedair investigates. The Capellan teer agrees.
Kedair scans the site, then interviews all witnesses; she learns that the last Ferengi supply ship to Capella had been different than the previous few times, and had been delivered by a woman. Greenblatt says the graffiti left by the toora Maab was made by a jorni plant; Lonnoc scans the area and detects some in a nearby cave. Inside the cave she finds a Capellan man, who throws a bladed kligat into her chest; luckily, Takarans are hard to kill. He admits to being the toora Maab, and is placed under arrest, awaiting the teer's judgement.
Helkara reports back that Kedair's scans showed that the explosive chemical was not cabrodine, but nitrilin modified to look like cabrodine. Nitrilin is only found on a Ferengi planet, and only the Breen have technology to mask compounds like this. The investigation concluded, Dax agrees to hand over the equipment.
The captain of the Kovlessa is arrested on Cestus III after it's discovered she was using a drug to alter her DNA in order imitate the deceased captain of the Kovlessa, Captain zh'Ranthi. The imposter, Torethirala zh'Vres, was arrested by Ferengi authorities for fraud, but released when they were bribed.
Pran arrives at Maxia Zeta IV and speaks with Captain Dayrit and XO Hadzic of the Musgrave. They've already figured out that the Ferengi woman named Sekki is responsible for the farantine and are trying to track her down. Dax interrupts to chew out Pran for running off with the runabout, for which he apologizes, but says they need to contact the Palais immediately. Sonek fills in Piniero about everything they've found, and she tells them about zh'Vres. Ultimately, they decide the next step is to track down Sekki.
Klag's fleet is one of the few in the KDF to have the newest cloaking tech that can counter the Kinshaya's anti-proton scans, so they go undetected at Krios. They launch their attack, quickly destroying 2/3 of the Kinshaya force. However, 6 new ships decloak: 2 Breen, 2 Gorn, and 2 Tzenkethi, and the 4 Klingon ships besides the Gorkon are destroyed. With a captured Kinshaya vessel in tow, Klag decides to retreat--but 3 more Klingon vessels decloak, having completed their escort mission, and turn the tide of the battle. All enemy ships are destroyed, save for a Tzenkethi vessel that cloaks and retreats.
Ambassador Derro replies back saying he has nothing to say to Pran. He contacts Dax to give her the bad news, but she gives him more: his wife Rupi was killed on Ardana during an earthquake. Despite his obvious sorrow, he says he still has a duty to perform and tells her about Derro; she says give her an hour.
An hour later, Derro contacts Pran and says Sekki recently bought a mansion on Thalezra. Derro's price for the info is that Pran tell Dax his intel was valuable, which he does; howeever, Dax says Derro has a long way to go before his debt is paid. Aventine and the runabout head to Thalezra. Pran tells the Musgrave they're leaving, and the Captain says that with the sensor data Dax provided, they should have the dilithium mine running in 24 hours.
Sonek contacts his estranged son Ayib. His sister already told him about his mother's death, and Pran apologizes for not telling Ayib himself. Pran says he'll see him on Mars for the funeral, and Ayib thanks him for calling.
Altoss hacks into the Thal database and finds the location of Sekki's mansion. 11 hours later they reach Thalreza, disguised as Lissepians to get past orbital control. Pran and Altoss beam down and find the mansion nearly empty; however, in an upstairs bedroom, they find Sekki's body, and her computer, which has been wiped. They discover a hidden safe filled with coins that say "TYPHON PACT" on them. Just then the Aventine arrives; Pran tells Dax they need to get back to Earth right now.
Bacco meets with Ambassador Tezrene of the Tholian Assembly. She shows her the Typhon Pact coins and says she knows that the Romulan Star Empire, the Gorn, the Breen, the Tzenkethi, the Kinshaya, and the Tholian Assembly have formed the Typhon Pact, but she doesn't understand why. Tezrene says it's because of Bacco: when she asked them to join the force at the Azure Nebula, she convinced them that they would be stronger if they stood together, and since none of them wanted to join the Federation or Klingons, they started their own government.
Bacco holds a press conference about the Typhon Pact. She says a summit will be held on Zalda in 2 weeks with the Klingons, Imperial Romulan State, Ferengi Alliance, Talarian Republic, and Cardassian Union to discuss an expansion of the Khitomer Accords to include those other governments.
Epilogue: On Mars for the funeral, Sonek tells Ayib that he loves him, and that they owe it to Rupi to try and talk every once in a while, even if there's not best friends.
