Reporter Jane Arden goes undercover to try to expose a gang of jewel thieves and smugglers. Her mission becomes more dangerous when her identity is discovered early on by one of the gang leaders.

When a rival newspaper publisher complains to his captain about possible collusion between himself and reporter Torchy Blane on scooping her rivals in crime news reporting, Det. Lt. Steve McBride determines to thwart her efforts to get inside information - and she determines to go on getting it, by whatever means necessary.

Choreographer Bob Connolly and prolific screenwriter Crane Wilbur teamed up on the direction of Warner Bros.' The Patient in Room 18. Patric Knowles delivers a delightfully comic performance as Lance, an outwardly normal young man obsessed with detective stories. When his obsession threatens to lapse over into lunacy, Lance is sent to the hospital for a nice long rest. It isn't long before he gets mixed up in a genuine murder mystery, using his second-hand knowhow to solve the case. Up-and-coming Ann Sheridan is quite amusing as Lance's nurse and confidante, while the murderer is played by a fellow who is usually cast as the murder victim.
