Description: Johnny Worricker (Nighy) is a long-serving M15 officer. His boss and best friend, Benedict Baron (Gambon), dies suddenly, leaving behind him an inexplicable file which threatens the stability of the organisation.
Meanwhile, a seemingly chance encounter with Johnny's striking next-door neighbour and political activist, Nancy Pierpan (Weisz), seems too good to be true. Johnny is forced to walk out of his job and then out of his identity to find out the truth.
David Hare says: "The last decade has been as testing as any in the history of the British intelligence community – the compromises and dilemmas they've faced in the new century make a fascinating story. I'm thrilled to be working with such an extraordinary ensemble of great actors."
David Hare is also an Oscar-nominated screenwriter (The Reader, The Hours).
