A boy will have to face his fear of swimming when a marine zoo starts to collapse after an underwater volcano becomes active. The Rescue Heroes will have to save both human and aquatic life before the disaster hits. A boy who idolizes the Rescue Heroes learns that heroes come in all shapes and sizes. His father, the town sheriff, will assist Billy when his son needs to be rescued during a hurricane. His father learns a lesson as well: that the Rescue Heroes are not what he originally perceived.
