No way up

Intro On a Vista Airlines flight from LAX to Los Cabos, the plane hits birds and crashes into the Pacific Ocean killing both pilots, along with several passengers. The remaining survivors, Ava (the daughter of a prominent politician) and her boyfriend Jed, Jed's friend Kyle, a young girl named Rosa traveling with her grandparents (her grandmother survived), Ava's personal bodyguard Brandon and flight attendant Danilo, find themselves trapped inside an air pocket at the rear of the fuselage as it sinks to a rock base underwater. At first, Brandon takes charge, telling the survivors they must stay put and await rescue. On his way to retrieve an oxygen tank from the front of the submerged plane, a tiger shark attacks Brandon through an opening in the side of the fuselage. He manages to escape back to where the survivors are waiting, but is soon dragged back underwater by the shark. Kyle's arm is severely injured in the crash, so the girl's grandmother, Mardy, “Nana,” a former army nurse, treats it in the aft galley with a makeshift splint. Meanwhile, a rescue crew arrives by helicopter to search for the missing plane. The remaining survivors argue over what their next course of action should be, figuring they should do what Brandon would have done. Ava reasons they have 3 or 4 hours of air left before they run out. Jed explains that eventually the structural integrity of the fuselage will not hold and crush them inside. At that moment, the wreckage slides down the rock face, dragging them deeper into the ocean before coming to rest on the edge of a cliff leading into a dark abyss.
