J. L. "Fatman" McCabe is a Hawaii-born, tough former Honolulu Police Department officer turned Los Angeles district attorney. He is teamed with a handsome, happy-go-lucky special investigator named Jake Styles. They often clash due to their different styles and personalities. "Fatman" travels hardly anywhere without Max, his pet bulldog. The show was set in Los Angeles during the first season. After the end of Magnum, P.I., the show was moved to Hawaii. The second and third seasons and half of the fourth season were filmed in Honolulu. The show then returned to Los Angeles for the remainder of its run.
