Twenty-something sisters Kate and Lisa are gorgeous, fun loving and ready for the holiday of a lifetime in Mexico.
When the opportunity to go cage diving to view Great White sharks presents itself, thrill-seeking Kate jumps at the chance while Lisa takes some convincing. After some not so gentle persuading, Lisa finally agrees and the girls soon find themselves two hours off the coast of Huatulco and about to come face to face with nature's fiercest predator.
But what should have been the trip to end all trips soon becomes a living nightmare when the shark cage breaks free and sinks and they find themselves trapped at the bottom of the ocean. With less than an hour of oxygen left in their tanks, they must work out how to get back to the boat above them through 47 meters of shark-infested waters.
