When working with the Mounties, The Inspector becomes the prisoner of the ever alert fugitive, Caribou Lou.

Inspector Clouseau is posted with the Canadian Mounted Police to study their crime investigation system and is assigned to apprehend a villain named Two-Faced Harry, who actually has two faces, one deceptively honest-looking, the other malicious. Clouseau doesn't realize these two faces are of the same man until he has chased the two-faced freak into the snowy plains of Manitoba.
