Watch and Warn is ground zero history. It' s an untold story about ordinary Canadians who, in the daily routine of their lives, volunteered to keep a close watch for enemy threats to our country during World War II. Housewives, school children, fishermen and lighthouse keepers became official observers for the Aircraft Detection Corps (RCAF). Interviews with former Observers, citizens and RCAF personnel are combined with archival images to convey those anxious years when the war came very close to home.
