Witness for the Prosecution

The affable Leonard Vole (Tyrone Power) is being tried for the murder of a wealthy woman, and legendary lawyer Sir Wilfrid Robarts (Charles Laughton) has chosen to represent him. Unfortunately, Leonard's alibi depends on the testimony of his callous wife, Christine (Marlene Dietrich) -- who, after the discovery of a legal loophole, makes the shocking decision to appear in court against him. To Sir Wilfrid's surprise, this is only the first in a series of puzzling revelations and reversals.
