The Virginian S01E13 - The Accomplice

The Rocky Point Bank is robbed by two men who shoot its President. One of the men is captured and claims Trampas, with whom he has a grudge, was his accomplice -- so Trampas is arrested. His identification as the robber is supported by a spinsterish bank teller, Delia Miller (Bette Davis), who has recognized the real robber and is protecting his identity in order to blackmail him. The Virginian tries to prove Trampas innocent and expose the real criminal by falsifying Delia's story.
