Near the town of Lunenberg, Novia Scotia, a young boy witnesses an horrific crime. Years later, Scottish journalist John Taggart is headed for Canada to cover one of the biggest stories of his career, haunted by the mystery of his origins. He never knew his father's identity and his mother's mental decline now means it will never be revealed. Meanwhile Annie Welles, an officer in Nova Scotia's Major Crimes Unit, is faced with two curious murders, while a corrupt superior plots to end her career. When Annie and Taggart meet, they are both at turning points in their lives, and both are about to become involved in a conspiracy that will change them forever - if it doesn't kill them first.
