Possessed

In a rare unglamorous role, Joan Crawford stars as Louise Howell, who stumbles through the streets of Los Angeles in search of a man named David (Van Heflin). After passing out from exhaustion, she ends up in a psychiatric hospital. The unhealthy love she carries for David -- despite her marriage to her employer (Raymond Massey) -- is soon revealed in a series of flashbacks and paves the way for a psychotic breakdown that leads to murder.
