PLOT
Roberto (Luigi Giuliani) and Luisa (Rocío Durcal) are a couple but are not as sincere as they should be. She tells him she works at Telefónica when she actually sells cigarettes at "The Green Windmill" cabaret. She's surprised when she discovers plans for a bachelor party there in honor of Roberto, who is marrying a wealthy heiress. In revenge, Luisa adopts the role of Luisito and faces Roberto in disguise.
