The original format, set in Los Angeles, relates the exploits of Joe Mannix, an investigator for Intertect, a computerized private detective organization. After one year, the format changed to depict the investigations of Mannix as an old-school, Chandleresque private detective working out of his home at 17 Paseo Verde, Los Angeles. Helping him in his new role as an independent investigator was his secretary, Peggy Fair.
