Jesse, age 14, has been adopted by his foster parents, the Greenwoods, and they have moved from Seattle to the Pacific coast. He is given a job at the Misty Island Oceanic Reserve, a local wildlife rescue and research institute where Randolph, his Native American mentor from the movie, now works. In the first episode, Jesse discovers he has the ability to talk to animals and understand their speech; Randolph, a Haida people, explains that he is a Truth Talker. This revelation allows for Willy and the other sea creatures featured in the show to have full personalities and more prominent roles in key plot events. Jesse and Randolph work with Mr. Naugle, the head biologist, and Marlene, a research assistant, who are studying Einstein, a dolphin, and Lucille, a seal, teaching them behavioral communication with normal humans.
