Quartet

The titular quartet consists of novelist Isabelle Adjani, her Polish husband Anthony Higgins, wealthy philanderer Alan Bates and Bates' artist wife Maggie Smith. Though she's been indulgent of Higgins' past indiscretions, Smith isn't keen on her husband carrying on an affair with Adjani under their own roof. Meanwhile, Higgins sits in prison, jailed for his various petty thefts. Once Higgins is released, he learns about the Bates-Adjani-Smith contretemps. (allmovie.com)
