MISTY WITLOW, an aspiring actress, heads to the beach near Los Angeles to enjoy the sun and videotape a greeting to send home to her mother. An enormous shark, pale white in color, surfaces in a deep channel near her. The massive beast, larger than a school bus, glides past and rams the rocky outcropping she is standing on.

​

Terrorized, she scrambles back, away from the exposed jaws containing rows and rows of teeth bigger than her hand. Her camera continued to roll, recording the fish, as its jaws clamped down hard enough on the rocks to shake the ground under her, and, knock one of its teeth loose.

​

She is the sole witness to a killing machine thought to have been extinct for millions of years.
