They were headed for a dangerous and secluded surf spot, but the two girls were competing with other surfers and battling big waves too much to notice. The big waves soon turn into a big storm, and a hard fall leaves one girl too injured to make it to shore. The friends swim to a nearby sandbar to ride out the storm with only their surfboards for protection. To make matters worse, they realize that shark-infested waters stand between them and the safety of the beach!
