The story involves a Madrid screenwriter, whose life is being ruined by unauthorised circulation of his sexual fantasies on tape, and a police detective's wife who snatches quick moments with strange men.

[1] Javier, a freelance screenwriter, and Miranda, a telephonist at a radio station, meet one evening at a therapy group to combat sex addiction.

Javier's wife has left him because he was tricked by a woman called Azucena into recounting his sexual fantasies over a phoneline and cassettes of his imaginary activities are on sale throughout Madrid.

Miranda, while walking her dog after her husband has gone to work and her daughter to school, can't resist quick encounters with men.

After putting all her sleeping pills into Félix's soup, Miranda goes with luggage and dog to the hotel where Javier is staying.
