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.

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.

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.

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.

Ava retrieves a bag of scuba gear from the baggage area underneath the plane and the survivors prepare to swim to the surface.

Kyle explains he's too afraid to swim to the surface, recounting a moment in his childhood where he dove to the deep end of a pool and was too scared to resurface.

Rosa tosses her stuffed animal back into the ocean as a tribute to her grandparents and the other dead passengers as the helicopter flies off to safety.
