Plot
Persistent exposure of ocean wildlife to a toxic goo used in oil drilling leads to a shark growing in size and becoming bulletproof, and even attaining the ability to move around on land. It destroys the oil rig that caused it, and then moves to Los Angeles where it eats several divers and threatens to disrupt a bikini contest.
Marine biologist Dr. Catherine Carmichael hires captain Chuck, a local drunk, to drive her out to the oil rig, owned by Traymore Industries, to investigate. Meanwhile, two female lifeguards plan to drink and have casual sex, and a kite surfer is eaten by the "super shark". Carmichael takes a water sample, then confronts the CEO of Traymore who invites her for drinks and dinner. When Carmichael interviews the sole survivor from the oil rig accident, it is disclosed that highly harmful chemicals were used to bore through the rock and that a shark pulled down the rig.
Meanwhile, Carmichael tells the CEO what she thinks happened: a "hydrolizing agent" caused the oil rig to crumble. Soon, a US Navy submarine disappears, and a search plane spots the super shark. At the bar, the two female lifeguards are joined by the male lifeguard, awaiting the bikini contest. Back out on the ocean, Carmichael and skipper Chuck are circled by the super shark until Carmichael, acting on a hunch, tells Chuck to turn off the radio, after which the super shark leaves. She speculates that the fish was attracted to radio waves and sent out signals which disturbed radio reception.
