On a vacation getaway to the paradise beaches of Mexico, two sisters, Lisa and Kate, decide to embark on an exhilarating activity: cage diving with sharks. The idea of swimming so close to these majestic predators seems like an unforgettable experience. However, what starts as a day of fun soon turns into a nightmare.
After a small incident, the cage in which they are trapped shifts and sinks to a depth of 47 meters in the dark ocean. The situation becomes critical when they realize they are completely alone, with their tank air rapidly depleting and the threat of sharks lurking. The two sisters must confront their deepest fears as they fight for survival in a hostile environment.
With the pressure of the sea and the imminent danger of the sharks, the tension rises to a peak. Lisa, on the other hand, begins to question her confidence and ability underwater, and every second counts as she faces the possibility of not making it out alive from this adventure. The story not only tests their physical resilience but also their sisterly bond. The struggle to reach the surface will become an exciting, adrenaline-fueled battle where every rising bubble raises the question: will they manage to escape or will they be devoured by the ocean's most feared creatures?
