Dave Garver (Clint Eastwood) is a late night disc jockey in Carmel, California. Whilst his girlfriend is out of town he meets and beds a fan named Evelyn (Jessica Walter) who turns out to be the mystery caller to his show who sexily requests the Errol Garner classic tune "Play Misty For Me". Thinking that his night of passion with Evelyn is purely a one off, he starts to become concerned as Evelyn refuses to leave him alone, and things are about to get very out of hand and become very disturbing for all involved.
