Pardon My Past is a 1945 American comedy film directed by Leslie Fenton and starring Fred MacMurray, Marguerite Chapman and Akim Tamiroff.
Eddie York and Chuck Gibson are two ex-soldiers leaving the service to become mink farmers in Beaver Dam, Wisconsin.
The thug holds Eddie and Chuck at gunpoint and makes them follow him to Arnold, where the bookie claims his money back.
Awaiting someone who can help them open the safe, the two men are invited by Joan, a young woman who is a distant relative to the family, to stay the night at the mansion.
Uncle Wills, the man with the safe combination, arrives in the morning, and is stunned by the audacity of Francis, who usually is much more evasive and timid.
Wills suspects that Francis has lost his mind and tries to commit him to a psychiatric ward, but fails as Eddie escapes his clutches.
When Eddie goes to the tailor again to fetch his new suit, Arnold meets him there, furious over the fact that Wills' check bounced.
It turns out Wills has managed to get Mary arrested for trying to kidnap Stephanie, and the police bring her to the mansion.
