"The Ghost Writer" tells the story of a former British Prime Minister, Adam Lang (Pierce Brosnan), who is holed up on an island off the Eastern seaboard of the U.S. in midwinter, writing his memoirs. When his long-standing aide drowns, a professional ghostwriter (Ewan McGregor) is sent out to help him finish the book. The anonymous ghost writer is quickly drawn into a political and sexual intrigue involving Lang’s wife, Ruth (Olivia Williams) and his aide (Kim Cattrall). Hanging over Lang is the threat of a war crimes trial and a mysterious secret from his past that threatens to jeopardize international relations. The film is based on the Robert Harris novel "The Ghost."
