Desperately Seeking Susan 1985

Every man is desperate to have her. One woman is desperate to be her. But someone is desperate to kill her. If they can figure out who she is.

Directed by Susan Seidelman

A bored New Jersey suburban housewife's fascination with a free-spirited woman she has read about in the personal columns leads to her being mistaken for the woman herself and into a chaotic adventure of amnesia and self-discovery.
