This children's story of a dog and a dolphin borrows heavily from family movies of the past. Zeus is a dog who follows a neighbor, a marine biologist named Mary Beth (
Kathleen Quinlan), to work one day. Aboard a ship, the dog meets Roxanne, a dolphin that Mary Beth is studying. When she sees the dog riding on the dolphin's back, she decides to study their friendship. A villainous fellow researcher, Claude (
Arnold Vosloo), tries to steal her research, but he is thwarted by the dolphin, the dog, and the dog's young owner, Jordan (
Miko Hughes). Terry (
Steve Guttenberg), Jordan's father, is a songwriter who still pines for his dead wife. Jordan, together with Mary Beth's daughters, try to ignite a romance between their parents, who are both unattached. ~ Michael Betzold, All Movie Guide
