Based on actual cases from the San Francisco Police files, Lt. Guthrie and Inspector Grebb work as a team to track down criminals. In the last season Inspectors Delaney and Summers are partners in the pursuit of justice. Frequently a police lineup is featured.
Jim Paisley and his gang break into a gun shop stealing numerous firearms, then go on a crime spree. It's up to Lt. Guthrie and his men to find him and get back the guns before the gang can do too much damage.
