Years ago NY gangsters Martin (Pat O'Brien) and Dane (Wayne Morris) got away with killing a rival and now have legitimate businesses. However an ambitious DA has new evidence and has persuaded Dane to shop his old mate Martin in return for immunity. Martin confronts Dane and ends up injured and on the run after a shoot-out.
Hiding from the law Martin finds and befriends a one-eyed dog which he names Johnny. By coincidence the dog is the pet of Elsie (Gayle Reed) the daughter of Lily (Dolores Moran) who is Dane's current squeeze...
The film starts off very Noir indeed though when Elsie is introduced we nearly drown in sentimentality and little girl cuteness. Lose the Elsie sub-plot and the film would have been much better and a tough gangster tale, as it is it's rather uneven but worth persevering with.
