While vacationing in the tropics, a group of teen-agers set sail to an apparent deserted island. What they discover when they arrive is that the island is owned by Dr. Balleau, an eccentric man with a passion for big-game hunting. After years of importing game onto the island for sport, Dr. Balleau has set his sights on new quarry, those unfortunate enough to stumble upon his island. Now realizing what they're up against, the teen-agers must elude their host in the hopes of making off the island alive.
