Nancy visits an unfrequented shoreline for a day of surfing. While she catches waves in a picturesque setting, an enormous shark attacks her. The shark attempts to maul Nancy, leaving her stranded on a small rock in the ocean. An injured Nancy is less than 1,000 feet from shore, but the shark refuses to abandon its potential prey. Unfortunately, Nancy finds herself stranded on a partially submerged rock, and she has limited time to reach the shoreline. A straight break for the beach won't work, so Nancy is forced to outwit one of the ocean's biggest predators and greatest threats.
