Synopsis by Hal Erickson
The Countess Framboise (Ann Sothern), aka Lucy's old school chum Rosie Hannigan, is now selling real estate. Lucy (Lucille Ball) tries to help her friend land a big commission by inveigling Mooney (Gale Gordon) into renting an "ultra-modern" apartment. Unfortunately, the apartment's door locks automatically for the weekend, leaving Lucy, the countess, and Mooney trapped with no food or water for three days! This episode actually marked the first of three appearances this season of Ann Sothern as the countess, but was telecast second for the sake of continuity.
