Chief Dan Mathews is a tough guy with a gruff voice fighting crime somewhere in the West in a gritty series lent much dramatic heft by Oscar winner Broderick Crawford ('All the King's Men'). A major hit in syndication, the show is memorable for its framing of tight shots, quick-cut edits and Crawford's Buick Special, which he seemed forever to be leaning against, shouting into his two-way radio, '10-4! 10-4! 10-4!'
