Paul (François Cluzet) and Nelly (Emmanuelle Béart) have what appears to be the perfect life; happily married, a wonderful son and a successful business in their idyllic lakeside hotel. For Paul it all seems too perfect and he begins to suspect his wife of having an affair. Tormented by nightmares and visions his paranoia soon threatens Nelly as his jealousy descends into madness. Directed by the French master of cool thrillers Claude Chabrol, L'Enfer was scripted by the great Henri-George Clouzot (Les Diaboliques, Wages of Fear) and stars Béart in one of her finest performances.
