Linda Blair

When an in-flight collision incapacitates the pilots of an airplane bound for Los Angeles, stewardess Nancy Pryor is forced to take over the controls. From the ground, her boyfriend Alan Murdock, a retired test pilot, tries to talk her through piloting and landing the 747 aircraft. Worse yet, the anxious passengers — among which are a noisy nun and a cranky man — are aggravating the already tense atmosphere.

A teenage girl once possessed by a demon finds that it still lurks within her. Meanwhile, a priest investigates the death of the girl's exorcist.

Twelve year old Regan MacNeil begins to adapt an explicit new personality as strange events befall the local area of Georgetown. Her mother becomes torn between science and superstition in a desperate bid to save her daughter, and ultimately turns to her last hope: Father Damien Karras, a troubled priest struggling with his own faith.

When two girls disappear into the woods and return three days later with no memory of what happened to them, the father of one girl seeks out Chris MacNeil, who's been forever altered by what happened to her daughter fifty years ago.
