Skipper is a goldfish who dreams of escaping his small tank to live freely in the underground rivers. He hears stories from other fish at the pet store of those who dared to jump to a different tank and either succeeded in their dream or died trying. Skipper has devised a plan to jump from his tank to a nearby tank, and then to the toilet, which will lead him to the rivers. After training vigorously, Skipper is ready to attempt the first jump in his daring escape plan.
