Popular film director Pablo Quintero (Eusebio Poncela) has found a new love in the form of handsome blue-collar Juan (Miguel Molina). Not altogether comfortable with his lifestyle, Juan decides to leave Pablo for a while to contemplate his future. Pablo insists that Juan keep in touch by sending him love letters. Ever the director, he plans to write the letters himself, and have Juan mail them back with his signature. If you think that settles things, you don't know filmmaker Pedro Almodovar. Among the many plot complications in Law of Desire is Pablo's subsequent romance with the possessive Antonio (Antonio Banderas, whose "gay kiss" in the film prompted front-page headlines in the Brazilian press), and Pablo's efforts to film the life story of his sister (Carmen Maura), who started out life as his brother.
