In a small provincial town on the Spanish coast, a conflict arises between prostitutes and a group of devout women, annoyed by the presence of prostitutes in their locality. The tension is increasing and the prostitutes are asking Carmelo, the local pharmacist, to intercede for them. He, who goes out with Asunción, one of the women facing the heteros, refuses. To convince Carmelo, prostitutes force him to have sex with them. Due to the pleasure of this experience he changes his mind.

En una pequeña ciudad costera se desencadena una curiosa guerra entre las "virtuosas" y las "prostitutas", eligiendo éstas a Carmelo (Ricardo Merino), dueño de la farmacia del lugar, para que medie, a lo cual él se niega por tener a su novia, virgen, en el otro bando. Una noche las prostitutas violan repetidas veces a Carmelo, el cual, ante tan tremenda experiencia cambia de forma de pensar.
