Against the backdrop of WWII, no one expected to find a murdered stagehand on a Warner Brothers sound stage. With so much at stake, Jack L. Warner hires Babs Norman and Guy Brandt, the two young private eyes who recently resolved his high-profile Maltese Falcon/Blackbird Killer Case. Social justice crusader Leon Lewis suspects local Nazi sympathizers are responsible. Lewis assigns a German stuntman, a veteran of the decadent subculture of Weimar Berlin nightlife and one of his newest operatives, to join forces with the private detectives.

According to Warner, the show must go on, but everything from bomb scares to the Japanese internment, to unruly parrots, forbidden love, and family crises conspires against solving the crime. "As Time Goes By," actors Humphrey Bogart, Ingrid Bergman, and the rest of the Casablanca ensemble join the professional private eyes to round up the unusual suspects and capture the killer.
