No desearás al vecino del quinto (1970)

Pedro, a handsome gynecologist who lives in Toledo (Spain), does not have just a clientele due to the jealousy that his sex appeal causes in the husbands and boyfriends of his patients. To make matters worse, his mother still treats him like a child and the traditionalist members of his girlfriend's family don't look kindly upon Pedro. But on a trip to Madrid to attend a conference on medicine he meets Antón, his effeminate neighbor of the fifth floor, whose fashion boutique for women thrives thanks to the complicity he knows to establish with his customers.
