About 125 years ago, give or take a few , French musicians visiting the Golden State, heading down from San Francisco, to the mythical city of San Diego ( never heard of it either), Hollywood apparently, never arises, are kidnapped by promises of comfort and help, when they are marooned, in a small village in southern California, only two miles from the coast, to a city that nobody seems to know. The Concerting Quartet, all close friends, desperately need shelter and food, Sebastien Zorn, the grouchy cellist and leader, also the oldest member, Yvernes, the first violinist, Frascolin, the second violinist, and the curious Pinchinat, who plays the viola. Chamber music has become a craze in the United States ( this is a fantasy of course), but Mr. Calistus Munbar, seems like a trustworthy fellow ( far from it), a music lover though, can help the Frenchmen , he says, get to this unknown town ... And with plenty of time left, for their next... engagement.They cross a "river", and arrive at Standard Island, really a massive ship miles long and wide, made of steel, with a population of 10,000, American millionaires and billionaires. Hundreds of propellers power this strange island, they're enthusiastically welcomed to modern , Milliard City, electrified, tall buildings, extended , clean streets, great mansions, upscale stores, green parks, an impressive observatory, too, even animals and birds , and crops grown, also, go anywhere in the vast Pacific Ocean, where the rich want, visit numerous islands, archipelagos inhabited by half - civilized natives, beautiful, sandy beaches, exotic wildflowers, mountains thousands of feet high, waterfalls, cascading down into the mists, thick forests, blue skies, gorgeous, coral atolls, rising from the bottom of the sea, extinct volcanoes, and some very active, and the ever present, quite annoying mosquitoes... An independent nation, with no borders, but the salt water, freedom, climate always fine, they choose the best areas. The giant structure immune from storms , they believe . Paradise, not, two quarreling groups fight for supremacy, the Starboard section (west), led Mr. Jem Tankerdon , Protestant , northerner, and Larboard ( Port, east), led Mr. Nat Coverley, Catholic, from the south, the two riches men on the self-propelled island, hate each other. Both are jealous, stubborn, and silly, will not cooperate, and run the floating island, in a manner not for the good, they would rather destroy it, still these gentlemen have a young son and daughter, Walter Tankedon, and Miss Dy Coverley, lovebirds, not of the same sentiments...The French musicians start to enjoy this unexpected voyage, bringing good music, to the wealthy, seeing exotic lands, primitive cultures, and even some cannibals, who have not given up their favorite meat. And the musicians are getting a million francs each, not a bad deal...if they can survive the waves from Standard Island, both the pirates, and the typhoon.
