Gleb, a Russian company director already unravelling under the pressure of laying off his own workforce, discovers that his wife Galina has been having an affair, a betrayal that triggers his complete emotional and moral collapse against the backdrop of the ongoing Russo-Ukrainian war. Reimagining Claude Chabrol's 1969 classic The Unfaithful Wife through a contemporary Russian lens, director Andrey Zvyagintsev, shooting in exile in Riga, Latvia, delivers an intimate drama of personal and political crisis that won the Grand Prix at the 2026 Cannes Film Festival, the director's third major Cannes honour following Leviathan and Loveless. A bleak, tightly controlled study of moral collapse that transposes Chabrol's classic premise into urgent contemporary Russian political territory, deservedly honoured with Cannes' Grand Prix.
