Due South - The Final Season (4th Season) - Region 0 DVD

This is the story of a Canadian mountie who went to Chicago to find his father's killer. Eventually the trail led back to another mountie. He was then treated as persona non grata by his other mounties, and the only place he could get posted was Chicago. Unfortunately, he is more of an outdoors kind of guy, which infuriates the Chicago detective with whom he works.
