Sam Ellis (Patrick Wilson The Conjuring, Fargo) is a man on the rise - a hotshot federal prosecutor on the cusp of a bright political future with a beautiful and ambitious wife (Lena Heady Game of Thrones). But what was meant to be a one-time experience with a high-end escort instead turns into a growing addiction. His moral compass unravelling, his new demon threatens to destroy his life, family and career, especially as Coaker (Ray Winstone), a seasoned hack and old family acquaintance, suspects his extra-marital exploits and plans to expose him.
