When club member Danny Dolan's brother Knuckles is sentenced to death row for killing a treasury agent, Pat vows to help Danny clear his brother, whom he believes is innocent, but before he can begin his investigation, the police commissioner demotes him to walking a beat.

Meanwhile, a counterfeiting ring composed of Mileaway Harris, a former tenement kid, Morris, and his girl friend May sets up shop in shopkeeper's Schmidt's, basement.

To prove his innocence, Pat takes to the streets, and Danny, still unaware of Morris' involvement in the counterfeiting ring, agrees to deliver a suitcase for him to May.

When they both fall to the sidewalk, Dutch is killed; but Mileaway lives to confess to the agent's murder, and all ends happily as both Knuckles and Pat are exonerated.

The film was originally released on DVD by Alpha Video on June 24, 2003 and has since been re-released multiple times by a variety of manufacturers.
