Sgt. Bob Fraser, a veteran Mountie, is on assignment in the isolated reaches of northern Canada when he is shot and killed. It is initially ruled a hunting accident--until Sgt. Fraser's son, Constable Benton Fraser, arrives and takes charge of the investigation. Fraser traces the gunmen to Chicago, and contacts the local law enforcement for help. Sgt. Fraser's case has been assigned to Detective Ray Vecchio, who feels he has more important cases in his workload.
