Plot
In Toledo, a provincial town near Madrid, Andreu, a handsome gynecologist, opens his practice without any success, as he is too attractive for the husbands and boyfriends of his patients not to be jealous of him. While Dr. Andreu fails miserably, the dressmaker Anton, owner of a boutique and with a reputation of being effeminate due to his manners and his little dog, makes the husbands feel confident in him, letting their wives shop in his boutique.

Dr. Andreu goes to Madrid to attend a gynecology conference and, dragged by his colleagues, decides to go to a cabaret. There, the doctor is frightened to see how Anton, his neighbor from the fifth floor, without a wig and displaying all his hidden masculinity, is having a great time between two beautiful women. When discovered, Anton confesses to Andreu that he pretends to be homosexual so as not to have problems with the husbands of his clients. Later he takes him to his apartment where, through a telescope, they flirt with two beautiful hostesses from the apartment across the street. Shortly afterwards they return to Toledo. There everything is gossip and provokes the same comment: what dirty friendship unites the gynecologist with the sensitive dressmaker?
