Janet (Kristin Scott Thomas) has just received an important position in British politics and is having a small party at her house to celebrate. Invited are her friend April (Patricia Clarkson), with her estranged German partner Gottfried, Women’s studies professor Martha, with her partner Jinny, a renowned chef, and Janet’s colleague Marianne with husband Tom. While the friends arrive, the party gets a dramatic turn when Bill (Timothy Spall), Janet’s husband, makes a shocking announcement. It turns out not to be his only secret and the other guests are dragged along in the accumulation of revelations and confrontations.
Love, friendship and political ideals are put at risk. As the sophisticated soiree starts to unravel, a night that began with champagne soon ends up with arguments, shouting, and a pointed gun. A both wry and hilarious portrait of a group of friends who see their certainties falling apart.
