Synopsis: Joan Crawford is appropriately cast as the title character in This Woman is Dangerous. Crawford plays master criminal Beth Austin, the lady friend of dangerous gangster Matt Jackson (David Brian). After being caught in the crossfire of a robbery engineered by Jackson, Beth recuperates in a hospital, hoping to keep her past a secret from the authorities. But the FBI wants Beth to lead them to Jackson, and to that end, her doctor Ben Halleck (Dennis Morgan) is strong-armed into inaugurating a romance with his gorgeous patient. Eventually, of course, Ben and Beth fall genuinely in love, thereby incurring the terrible wrath of the vengeful Jackson. And to think that Joan Crawford endures all this without a hair out of place on her lovely head! TV's future "Captain Midnight" Richard Webb co-stars as a diligent FBI agent.
