starring Alan Ladd, Veronica Lake, William Bendix
directed by George Marshall
Johnny Morrison (Alan Ladd) returns from serving in the South Pacific during World War 2. He finds that Helen, his wife, is carrying on with Eddie Harwood, owner of the Blue Dahlia, a nightclub. Helen turns up dead the next day. Johnny quickly becomes the number one suspect even though she had a couple other visitors that night.
Morrison goes on the run. He calls himself Jimmy Moore. That's the name he gives to Joyce Harwood (Veronica Lake) when she stops to give him a ride. She is separated from her husband Eddie. She doesn't give him her name and he has no idea who she is.
A few people are called in for questioning by the police, including Eddie Harwood and two of Johnny's friends (Buzz Wancheck, George Copeland). Buzz (William Bendix) went out looking for Johnny on the night Helen was killed. He ran into Helen and went back to her place, not realizing who she was, for a drink.
Harwood eventually gets the drop on Johnny. Two of his men, posing as policemen, pick up Johnny. Things don't go exactly as they had planned.
