As the shooting for his latest production wraps up, director Tomas (Franz Rogowski) celebrates in the company of his husband Martin (Ben Whishaw), the film crew, and their guests. Among the latter, is Agathe (Adèle Exarchopoulos), a young woman who invites Tomas to dance. Soon, the two begin a passionate affair, one that would not just put strain on the relationship between Tomas and Martin, but also resonate through the wider circles inhabited by the three main characters. Personal matters interrupt their professional lives, friends and family provide opinions - warranted or not - and the ménage à trois arrangement is put under further pressure as complications arise.—aherdofbeautifulwildponies
