Mismatched cousins Kaz and Truly barely survived their first alien invasion.
When the villainous Horde Empire returns, the space conquerors look twice as dangerous. This time, Maximo Skulldigg and the rest of the Horde have a tool to sideline the kids’ mysterious protector, cosmic knight Trinn Cyclo. To make matters worse, the Horde kidnaps Kaz’s parents!
If Kaz and Truly hope to rescue the grown-ups, they’ll need all the luck they can get. They’ll even need Kaz’s catlike, UFO-obsessed uncle, Lucky…
The Horde attacks and takes Kaz's parents so Kaz and Truly and uncle Lucky go after them. Kaz and Truly use their bands to call for help when they reach the hidden lair where their parents are being held. All kinds of chaos ensues as Cyclo, summoned by the cousins, battles the Horde depleting almost all his power giving the Savage family time to escape to safety. An exciting adventure.
