A loose remake of 1941's The Gay Falcon, The Falcon's Alibi is one of the better entries in RKO's "Falcon" series, and one of the few that can stand on its own merits as a "film noir." This time, amateur detective Tom Lawrence (Tom Conway), aka the Falcon, endeavors to protect wealthy journalist Henryette Alcott (Ann Richards) lobbies to bring Law and Order into Quinto. As it turns out, the villain of the piece is ruthlessly ambitious marshal Bill Hampton (Morgan Conway), who hopes to foment trouble between the outlaws and the peaceable settlers for his own political gain.
