When actress Mary Baring is found in a daze beside her colleague’s murdered body, all evidence points to her guilt. During the trial, juror Sir John Menier doubts the verdict, but yields to pressure. Haunted by remorse, he launches his own investigation. (Filmed in German on the same sets as Murder! (1930), this version was directed by Alfred Hitchcock with a new cast for international release.)

Trivia, insights & behind the scenes
Hitchcock filmed Mary and Murder! simultaneously on the same Elstree sets, directing German actors in the morning and English actors in the afternoon like some kind of maniac.
This was BIP Studios' attempt to crack the German market; ironically, Nazi censorship soon made such co-productions impossible, making Mary a fossil of Weimar-Hollywood collaboration.
