Deep Water

During an international flight from Los Angeles to Shanghai, an improperly stowed power bank ignites a fire in the aircraft's cargo hold, leading to an explosion that ruptures the cabin and destroys an engine. As rows of passengers are ripped out of the plane, captain Rich and first officer Ben are forced to make an emergency ocean landing. The aircraft strikes a coral reef, separating the survivors into three sections of wreckage.

In the forward section, Rich is trapped in his seat and places Ben in command, ordering him to escape before the cockpit fills with water. Hoping to retrieve the aircraft's E.L.T locator from the middle section of wreckage, crew member Penny swims out alone, but Ben and young passenger Cora are unable to save her from a shark.

Ben and Cora reach the middle section, as does passenger Lilly, who is reunited with her esports teammate Sam, but sharks continue to attack. With fewer than thirty survivors left, Ben organizes them aboard two life rafts, and is forced to take charge against the selfish Dan and the aggressive Hutch. Dan loses the locator in the water, while Sam and Hutch are narrowly rescued after being swept away.

In the submerged tail section, crew member Zoey, Matt, Becky, and Cora’s stepbrother Finn are trapped in an air pocket. Swimming to the surface to find help, Matt encounters Cora and Finn’s father, but they are attacked by a shark. Zoey escapes with Finn and promises to return for Becky, whose final thoughts are of her granddaughter. Finding Matt’s body, Zoey is attacked by sharks, but manages to board an abandoned life raft with Finn before losing consciousness. Unable to wake her, Finn falls into the water.

By nightfall, the survivors are located by a U.S. Navy rescue helicopter. A crew member is lowered into the water but quickly devoured by sharks, and the destablized helicopter crashes and capsizes a life raft. Dan pushes another survivor to her death to save himself, while Cora is trapped on the wreckage, and a Chinese fishing boat is unable to reach the remaining raft due to the coral reef. Swimming back with Cora, Ben is surrounded by sharks and kills one with a flare gun, while Dan is eaten as the fishermen throw their catch into the water, successfully luring the predators away.

The survivors are rescued by the fishermen, and Sam and Lilly admit their feelings for each other. Cora uses Ben’s phone to locate her stepbrother’s tracking chip, finding Zoey and Finn alive. Having originally requested the flight to avoid facing his own son’s illness, Ben tells his family that he is coming home.
