Jesse begins his new job at Misty Island Park. However, just as he meets Mr. Naugle, Randolph, and Marlene—the crew of the rescue center—he quickly becomes unpopular. His friend Willy, the orca, eats all the fish intended for the sick and injured animals. Shortly after, Jesse has a confrontation with Mr. Naugle, the center's director, and decides to quit his job abruptly. Then something extraordinary occurs: Jesse suddenly realizes that he can understand Willy, and the whale seems to understand him as well. Randolph, a Native American, explains to Jesse that there are children who can communicate with animals. Are Willy and Jesse soul brothers?
