Young Kirra Cooper (Bindi Irwin) is forced to spend a summer holiday far from her native Australia and with her unpleasant grandfather Gus Grisby (Beau Bridges) in South Africa. Gus tends to dress up as a pirate since he owns a small and inconsequential theme park called Pirate’s Cove, filled with unattractive exhibits. When Kirra finds a small Orca trapped in a nearby lagoon, Gus thinks they will be rich by exploiting it and selling tickets to the public. Kirra wants to free it, or at least protect it. When the whale becomes ill, she knows she must reunite the baby whale with its pod. She must convince her grandfather to help.
