Dan Chase distanced himself from the CIA many years ago and has since led a life outside conventional society. When a hitman shows up to eliminate Chase, the former spy discovers he must face up to his past to secure his future. Following Dan Chase's reappearance, Harold Harper, deputy director of the FBI's Counterintelligence Department, is tasked with tracking him down because of his complex history with the fugitive. Harper is assisted by his protégée Angela Adams and CIA special agent Raymond Waters. When Chase's capture proves more difficult than the authorities expected, Julian Carson, a highly skilled special operations contractor, is also sent to track him down. During his escape, Chase rents a room from Zoe McDonald, who draws on unsuspected resources to survive when she discovers the true identity of her new tenant.
