Johnny Stool Pigeon is a 1949 American film noir crime film directed by William Castle and starring Howard Duff, Shelley Winters and Dan Duryea.
The unlikely pair travels from San Francisco to Vancouver and finally to a dude ranch in Tucson which is run by mob bosses.
They end up getting help breaking the case from the gang leader's girlfriend (Winters), who falls for the narcotics agent during the sting.
Dan Duryea adds a surprising twist to his usual characterizations of tough hombres as the convict who turns on his own kind, and Shelley Winters gives a credible performance as the blonde moll who also gives the law a much-needed assist.
But aside from a few variations their crime and punishment adventures are cast in a familiar mold.
