Play it Again, Seymour (S01E09)

On April 14, 1953, Sam takes on the role of Nick Allen, a private detective with a striking resemblance to Humphrey Bogart. He's on a mission to uncover the killer of his partner, racing against time to avoid becoming the next victim. The investigation unfolds with several nods to Casablanca, and in the process, Sam helps launch a budding pulp fiction writer.
