A group of spring-breakers enjoying a weekend in Mexico. After a big night of partying on the beach until dawn, the friends steal a couple of jetskis and take them out to sea, but end up in a horrific head-on collision. After one of the jetskis sinks, the group finds itself stranded two miles from land on one remaining, broken-down jetski, and struggling with a badly injured friend. With no clear way home and predators circling in the choppy waters below, the true horror begins.
