Growing up in St. Augustine, Florida, siblings Kevin (Logan Allen) and Holly (Lola Sultan, whose spark radiates through every line) Ryan are always on the water and frequently see a mini-pod of dolphins. When Holly is in a boating accident, she's rescued by the dolphin the pair had named Bernie. When "Bernie" disappears, the siblings conduct a search for their missing friend. In the meantime, they stumble upon a real estate scheme to develop a nearby island and thus damage the ecosystem. Kevin and Holly must find a way to stop the real estate development, protect the sea animals' habitat, and save BERNIE THE DOLPHIN.
