The stooges do a good turn and help a stranger open a safe in what they think is the man's house. Actually the man is a crook and the boys were unwitting accomplices to a robbery. Once they realize what's happened, the stooges go after the bad guy and who's left on the train to Los Vegas. The boys trap the villain and recover the booty.
