The plot: Politician Janet (Kristin Scott Thomas), after being announced as the new shadow minister for health, is throwing a close-friends party at her house to celebrate. As the guests arrive, from her best friend April (Patricia Clarkson) and her partner Gottfried (Bruno Ganz) to professor Martha (Cherry Jones) and her wife Jinny (Emily Mortimer) as well as Tom (Cillian Murphy), the husband of one of Janet's co-workers, Janet and her husband Bill (Timothy Spall) do their best to try and cope with what will become a very turbulent and potentially fatal get-together.
