Sex, Lies and Videotape
(1989)

Ann (Andie MacDowell) tells John (Peter Gallagher) that she wants a divorce and then tells him she made one of Graham's (James Spader) tapes.

John, in a rage, storms over to Grahams house and watches the tape.

The tape never gets too explicit, but reveals the depths of both Graham and Ann's unhappiness.

In the end, Cynthia (Laura San Giacomo) and Ann dump John. They talk briefly at the bar and appear headed for a better relationship and Ann returns home to her new boyfriend, Graham.
