Description: American police drama about the investigations of Lieutenant Ben Guthrie and Sergeant Matt Greb. It was set specifically in San Francisco and was produced with the cooperation of the San Francisco Police Department, which received a credit at the close of each episode. It starred Warner Anderson as Guthrie and Tom Tully as Grebb. Grebb was now an inspector instead of a sergeant because at the time the series was made there was no such rank as sergeant in the Bureau of Inspectors, SFPD's investigative division, and a full inspector was the closest equivalent to the generic detective sergeant the character had been on radio.
