O'Hara, U.S. Treasury is a crime drama that aired on CBS.
O'Hara, U.S. Treasury starred Janssen (whose company co-produced the show with Mark VII) as the title character, Treasury Agent Jim O'Hara. Jim O'Hara was a county sheriff from Nebraska whose wife and child died in a fire, and to cut all ties with his past life, he put an application in with the United States Department of the Treasury; the Department accepted him. As a "T-Man," O'Hara was available for assignment to any of the various law enforcement agencies which were then part of the Department, all of which cooperated in this positive portrayal of their various organizations, much in the manner of the Los Angeles Police Department with Webb's Dragnet and Adam-12. These included the Secret Service, the Intelligence Unit of the Internal Revenue Service, the then-Alcohol, Tobacco, and Firearms Division of IRS, and the then-Customs Bureau. O'Hara sometimes worked undercover and sometimes overtly. Janssen was the series' only regular, as he was given a different assignment at the start of each weekly episode.
