Dark Passage

Vincent Parry (Bogart), convicted of killing his wife, escapes from San Quentin Prison and evades police by hitching a ride with a motorist named Baker. Already suspicious of Parry's appearance, Baker hears a radio news report about an escaped convict; Parry resorts to beating him unconscious. An apparent stranger, Irene Jansen (Bacall), picks Parry up and smuggles him past a police roadblock into San Francisco. She offers him shelter in her apartment while she goes to buy him some new clothes. Irene's acquaintance Madge comes by Irene's apartment, but Parry (through a closed door) tells her to leave. A former romantic interest whom Parry had spurned, Madge testified at his trial out of spite, providing a motive as to why he would have killed his wife. Irene explains that she had followed Parry's case with interest and that she believes Parry is innocent. Her own father had been falsely convicted of murder, and since then she has taken an interest in miscarriages of justice.
