Les amants terribles (1985)

This standard romantic drama focuses on three different couples who happen to come together in a small hotel in Rome and play out their differences in that setting. The couples are made up of a Parisian woman and her Slavic boyfriend out to spend some quality time together; a Frenchman (Jean-Noel Picq) searching for his sexually awakened teenage mistress; and a woman out to reunite with her Italian lover (Michele Placido). These people manifest different approaches to a romantic partnership that are tested in their brief encounters in Rome.
