The third of four Columbia shorts starring Joe DeRita, made across a period of 15 months from late 1946 to early-1948, has newlyweds Eddie (Joe DeRita) and Betty (Christine McIntyre) barely moved into their new house before Betty's mother (Esther Howard), aunt (Patsy Moran) and brother (Charles Williams) show up and give every indication of becoming permanent free-loading guests. Dick (William Newell) gives Eddie a plan that will cause his unwanted guests to vacate the premises, by having Dick and his wife, Ruby (Dorothy Granger), move in as Eddie's relatives, and even bigger pests, thereby causing Betty's relatives to move out. The plan works and Eddie and Betty are pleased until Dick announces that he and Ruby have intentions of staying on. A Spanish-language subtitled version was released as "La Suegra Intrusia."
