The Hawke family sets out on a private-yacht holiday with Tunya, Amy, and Tunya's fiancé Link. A sudden storm wrecks the yacht, stranding them on a tropical island. On the beach, a giant saltwater crocodile attacks, and Amy is killed. After they escape to higher ground, the grieving mother confronts Tunya. Just as Tunya is about to expose Link's conspiracy, he strikes first—smashing a stone into her head and framing her. Tunya's consciousness fades, and she is reborn before the disaster begins. Armed with full memory, she sees through Link and Amy's secret plot. The island crisis unfolds again, but this time Tunya is on guard, foiling their schemes one by one—using blood to lure crocodiles and murder her family to seize the Hawke fortune. On the cliffside, the conspiracy is fully exposed. A rescue helicopter arrives; Amy falls into the crocodile pack, and Link reaps what he sowed. Tunya protects her father and the captain, and they escape the deadly island alive.
