33 Half Moon Street - SA - The Girl in the Ascot Hat

Transcontinental Flight 17 is monitored by the police for a passenger identified as Boston Blackie, who is wanted for robbery. Blackie, who is being held in a hotel room, is approached by Miss Moray, who seeks his help to recover a stolen diamond crucial to her engagement. When she mistakenly identifies him as the robber of her grandfather, Blackie uses the situation to negotiate his escape and to assist her. Blackie eventually learns that the diamond was not stolen from her but was left with her fiancé, George Atwater. Blackie then orchestrates a plan to retrieve the diamond while avoiding police detection, leading to a confrontation with Atwater and a criminal named Duke Walton. The tension culminates in a twist involving fire and strategic deception, culminating in the retrieval of the diamond and Blackie's escape from the law temporarily, thereby ensuring Miss Moray's happiness.
