A reporter out to break up a criminal gang finds time to make a play for a mobster's girlfriend.

The Unseen Enemy in this wartime meller is Nick (Leo Carrillo), the outwardly effusive manager of a San Francisco waterfront café. To make enough money to ensure his daughter Gen's (Irene Hervey) entree into society, Nick sells his services to a gang of foreign spies, who then use Nick's establishment as a rendezvous point.

The spies' secret code is hidden in the lyrics of a song called "Lydia", which the unwitting Gen performs on request day after day.
