In The Lonely Woman (1973), a tale of bizarre sexual adventure, a young man (Renaud Verley) bounces from woman to woman--some young, some old, some crazy--in search of love and money. Director Francisco Rovira Beleta makes extensive use of body doubles in the various sex scenes, so there's a pretty good chance those breasts don't belong to either Maribel Martín or Concha Velasco. That said, they’re still professional body doubles with the bodies to match.
