When maladjusted orphan Jesse vandalizes a theme park, he is placed with foster parents and must work at the park to make amends. There he meets Willy, a young Orca whale who has been separated from his family. Sensing kinship, they form a bond and, with the help of kindly whale trainer Rae Lindley, develop a routine of tricks. However, greedy park owner Dial soon catches wind of the duo and makes plans to profit from them.
