Who’s that lady? This is what Alan Curtis and Ella Raines need to know. Alan is accused of murdering his wife, but he says he has a perfect alibi - he was spending the evening with a stranger at the time of the murder. Ella is determined to prove his innocence, and goes to great lengths to do so. Franchot Tone is along to help solve the mystery as well. It’s directed by Robert Siodmak and produced by Hitchcock collaborator, Joan Harrison.
