Produced by Rysher Entertainment, the film released theatrically in the United States on January 24, 1997, by Metro-Goldwyn-Mayer (MGM), grossing $7.2 million.

Later that morning, Zeus chases a cat and subsequently destroys the outdoor garden of Mary Beth Dunhill, a marine biologist and the Barnetts' next-door neighbor.

Mary Beth and Becky travel out to the ocean on a boat to follow the dolphin they are researching, whom they name Roxanne, and Zeus stows away with them.

During the following days, Terry begins to fall in love with Mary Beth as he manages to find inspiration for his music, while Jordan bonds with Judith and Nora.

Noticing his disappearance and realizing where he was going, Terry and Jordan return to town, while Mary Beth uses a submersible to go down and investigate the seabed after Claude claims Roxanne was caught in an illegal fishing net and killed.

While exploring the seabed, Mary Beth's submersible's propeller is tangled in the fishing nets, and when she opens the main hatch thinking she'd escape through it, water begins flooding the interior.

Zeus watches happily with Terry, Mary Beth, Jordan, Judith, and Nora as Roxanne leaps into the air with the pod.
