The Luck o' the Foolish.

Harry and Marcie are on a train headed for a new job. There's comedy in the berths and during Harry's morning shave, then a thief steals the money Harry needed for his new job, so he has to go back to being a beat cop and Marcie works as a seamstress. One evening, she delivers a dress to a party; a Lothario asks the hostess to get Marcie to stay. Outside the same house, Harry the cop is investigating strange noises. Thieves, bombs, a wallet, a swimming pool, and misunderstandings figure in the luck of our foolish but winsome pair.
