Absaroka ve Wyomingu je svérázný kraj na hranici divočiny. Najdete tu indiánskou rezervaci s původními obyvateli, krásnou přírodu, a pokud vás to nezaujme, najdete tu i takové výdobytky civilizace, jako jsou striptýzové kluby, organizovaný zločin, dokonce i trochu té politiky. S tím vším si musí poradit zkušený, zaprášený, kloboukem a kalibrem .45 vyzbrojený šerif Longmire. V případě potřeby volejte přímo na stanici, šerif totiž nevlastní mobil.

Lawman is an American western television series originally telecast on ABC from 1958 to 1962 starring John Russell as Marshal Dan Troop and featuring Peter Brown as Deputy Marshal Johnny McKay. The series was set in Laramie, Wyoming during 1879 and the 1880s. Warner Bros. already had several western series on the air at the time, having launched Cheyenne with Clint Walker as early as 1955. The studio continued the trend in 1957 with the additions of Maverick with James Garner and Jack Kelly, Colt .45 with Wayde Preston, and Sugarfoot with Will Hutchins. One year later, Warner Bros. added Lawman and Bronco with Ty Hardin.

Prior to the beginning of production, Russell and Brown and producer Jules Schermer made a pact to maintain the quality of the series so that it would not be seen as "just another western." At the start of season two, Russell and Brown were joined by Peggie Castle as Lily Merrill, the owner of the Birdcage Saloon, and a love interest for Dan.
