Frank Cannon isn’t your typical private detective. He’s overweight, likes to eat, drives expensive cars, and charges a lot of money for his services. But when you need a job done right and you don’t have a big enough gun… you call Cannon – a balding ex-cop with a deep voice and expensive tastes in culinary pleasures, who becomes a high-priced private investigator. Since Cannon’s girth didn’t allow for many fist-fights and gun battles (although there were many), the series substituted car chases and high production values in their place.
