Lisa becomes disoriented about her position. Javier attempts to usher her back towards safety but he is killed by a great white shark. Lisa takes his spear gun and the winch cable and swims back to the cage. The spare cable is attached but it snaps and the cage sinks back down, landing on Lisa's leg and pinning her. Kate tells Taylor they are low on air and Lisa is trapped. He sends air tanks down and tells them the coast guard is an hour out. He also warns that the second tank may cause nitrogen narcosis, which can lead to hallucinations. Kate finds three flares to signal the coast guard. As she returns to the cage, she is attacked and (presumably) devoured by a great white shark. Lisa uses the spear from the spear gun to pull a tank toward her and dons it, getting more air.
