Zachary Scott is an ex-cop with a bad case of alcoholism. He's a house detective at a sleazy hotel, sleeping one off, when his ex-wife, Faye Emerson wakes him to tell him their son has been kidnapped, his ex-colleagues are sympathetic, but it's up to Scott to track the abductors through the Skid Row world and rescue his son.... and himself.
This movie benefits from a strong, sympathetic story, and location shooting on the low-rent streets of downtown New York. There's a lot of talking, though, for such a usually visual genre, and the performances, while appropriate, are not terribly interesting. Scott and Miss Emerson start out with low-affect performances. Miss Emerson mumbles her lines in a tired and hopeless manner, and Scott spends the first half with subdued reactions. It's how a lot of depressives act, but it's not terribly interesting to watch.
The cast is eked out with some good performers, Mary Boland plays the sort of down-on-heels ex-floozie that Esther Howard usually did for Paramount Noirs, Sam Levene is the police captain who can't help because of the rule book, and J. Edward Bromberg, Kay Medford, and Jed Prouty have memorable roles. The result is a film noir that is highly watchable.
