Crossroads is a 1942 American mystery film noir directed by Jack Conway and starring William Powell, Hedy Lamarr, Claire Trevor and Basil Rathbone.

Powell plays a diplomat whose amnesia about his past subjects him to back-to-back blackmail schemes, which threaten his reputation, job, marriage, and future.

In 1935, rising French diplomat David Talbot and his beautiful much younger bride Lucienne are celebrating their third month of marriage.

They are interrupted by a note from the mysterious Carlos Le Duc demanding one million francs from David in payment of an old debt.

Talbot's strategy is foiled by a psychologist for the defense, Dr. Alex Dubroc, who tricks Tessier into conceding the unreliability of a diagnosis of amnesia.

Offended by David's hostile response, she shows him a locket containing a photo of the two of them together, adding that she will offer this important piece of evidence to Sarrou.

Allaine makes a surprise appearance at the Talbot home, implicitly threatening David with exposure and planting suspicions in the mind of Lucienne.

Still treating him as Pelletier, she accuses him of faking amnesia to justify the betrayal of his former friends, adding that his mother is living in penury in an adjacent neighborhood.

His doubts about his identity were laid to rest when, looking at his passport photo, he realized that the picture in the locket was a fabrication - allegedly taken before his accident, it shows him with a hairstyle he only adopted to cover the scar on his head.
