Paul Lohman (Coogan) and his wife Claire (Linney) go to dinner at a remarkably fancy restaurant with Paul’s relatively-estranged brother Stan (Gere), a high-powered politician, and his wife Katelyn (Hall) to discuss an incident involving their children. As secrets are unveiled through a series of flashbacks, what starts as a civilised get-together descends into sophisticated carnage as the characters reveal themselves layer by layer until the hidden violence at the core of civility is laid bare.
