6 minutes after takeoff, Flight 1421 crashes into the Pacific Ocean. During the evacuation, an engine explodes & the plane is flooded. Those still alive are forced to close the doors, but the plane sinks to the bottom with 12 souls trapped inside. More than 200 ft. below the surface, engineer Will Kent & his 11-year-old daughter Shannon are fighting for their lives. Their only chance of survival is an elite rescue team on the surface led by professional diver Chris Kent, Shannon’s mother & Will’s soon-to-be ex-wife, who must work together with Will to find a way to save their daughter & rescue the passengers from the sealed airplane, which is now teetering on the edge of an undersea cliff. There's not much time. There's even less air.
