Killer Sharks is a recreation of the world-famous attacks along the coast of Durban, South Africa, during the summer of 1957/1958. Called "Black December," these attacks partly inspired Peter Benchley's Jaws.

When Sara, a young design student from Iowa, arrives for college in Los Angeles, she is eager to fit in and get to know the big city. Her wealthy roommate, Rebecca, is more than eager to take Sara under her wing and show her the ropes. The two become close, but when Sara begins to branch out and make more friends on campus, Rebecca becomes resentful. Alarmed, Sara moves in with her new boyfriend, causing Rebecca's behavior to take a violent turn.
