Shemp and Rosco are husbands who married sisters and all live with the wive's mother. The husbands have been out late at night drinking and are trying hard no to make any noise as they slip back into the house, where the mother-in-law is guarding the door armed with a rolling pin. But they get into a neighbor's house and the lady in that house has a very large, jealous husband. (thetvdb.com)
