A ghost writer stumbles onto a secret that places his life in danger as he takes down the life story of a former U.K. Prime Minister in this Roman Polanski-helmed adaptation of the Robert Harris novel.

Convinced by his agent that he's been granted a once-in-a-lifetime opportunity, talented British screenwriter "The Ghost" (Ewan McGregor) agrees to aid British Prime Minister Adam Lang (Pierce Brosnan) in completing his memoirs after the leader's former aid dies under mysterious circumstances. Almost immediately after The Ghost arrives at a remote mansion in the U.S. to begin working with the prime minister, Lang is accused of committing a war crime by a former British cabinet minister. Amidst a deluge of protestors and reporters, The Ghost delves into the unfinished manuscript and comes to the terrifying conclusion that his predecessor died because he discovered a link between Prime Minister Lang and the CIA. The more information The Ghost uncovers, the more convinced he becomes that his life could be in danger as well.
