 For the last four years Margaret Holt has been helping her brother, assistant D.A. Victor Holt, to try to bring down the dope dealing Schemer Marko gang. Margaret kills Marko (aka  James Morton ) when he discovers she s found evidence to use against him. Looking for someplace to hide out, she flees to a local house for disadvantaged women. Her secret is discovered by gossip columnist John Howell and crotchety old mystery writer Winthrop Clavering, who concoct a plan to try to clear Margaret of the crime and, at the same time, capture the Marko gang, who have since kidnapped Victor and are now hot on Margaret s trail as well.
