Rod Cameron comes to town to discover his brother is dead and his widow, Vera Hruba Ralston, is being consoled by Mike Mazurki. The local cops tell him his brother was involved in the local drug trade, so Cameron agrees to stay on and help them crack the case.
It's Miss Ralston's last film appearance. Not entirely coincidentally, Herbert J. Yates was tossed out of his chairmanship of Republic Pictures. Nominally it was because of the strain of a shrinking market for B pictures and his unwillingness to release the Republic library to television. Miss Ralston almost certainly had a great deal to do with it. He tried to make her a star, a second Sonja Heinie, and had married her in 1952, but as an actor, she was a good ice skater, with a thick accent, no acting ability, and a middle-aged appearance. The fact that Republic spent a lot of money on her vehicles, and they didn't appeal to the public may have had something to do with the disappearance of husband and wife from the Republic lot.
And so might some foolish decisions in writing. While Cameron and the supporting cast, including Louis Jean Heydt, are pretty good, the big plot twist is given away by the title.
