London, 1934. Jimmy Erskine (Ian McKellen) is the most feared theatre critic of the age. He lives as flamboyantly as he writes and takes pleasure in savagely taking down any actor who fails to meet his standards. When the owner of the Daily Chronicle newspaper dies, and his son David Brooke (Mark Strong) takes over, Jimmy quickly finds himself at odds with his new boss and his position under threat. In an attempt to preserve the power and influence he holds so sacred, Jimmy strikes a faustian pact with struggling actress Nina Land (Gemma Arterton), entangling them and Brooke in a thrilling but deadly web of desire, blackmail and betrayal.
