Synopsis: This second entry in RKO Radio's "Falcon" series begins with Gay Lawrence (George Sanders), aka the Falcon, promising to give up his private-eye activities for the sake of fiancee Helen Reed (Wendy Barrie). This resolves lasts for about eight minutes, whereupon Lawrence tackles the case of a missing scientist named Waldo Sampson (Alec Craig), the inventor of a synthetic-diamond process. Kidnapped by Sampson's abductors, Lawrence manages to escape, only to be kidnapped again and later accused of murder. The resolution of the plot hinges on the old mistaken-identity device (one of the principal characters has an identical twin, and that's all that can be said without giving the game away). Carryovers from the first "Falcon" film include Allen Jenkins as Lawrence's dimwitted sidekick Goldie and character actor Hans Conried, here cast as a snotty hotel night clerk. A Date with the Falcon was unofficially remade as The Falcon's Adventure, the final entry in the RKO series.
