The law at Miles City

"Dave Horman, former lawman, is saved from a bullet by gambler Pete Green who expects a favor."@en
"Dave Harmon, former lawman, drifted into Miles City. After a casual conversation with well-known rancher, Jeffrey Munro, Munro is attacked by three toughs. When Dave tries to intervene, a fourth man clubs him with a pistol and is about to shoot him when Pete Green, a gambler, kills the attacker. Green wants no thanks from Dave but he does tell him that now he owes the gambler a life. Munro persuades the town council to appoint Dave as principal marshal. Pete Green urges Dave to take the job. It is uncertain how anything will play out, and Dave₂s future unfolds in a totally unpredictable, even dangerous way, one in which it becomes exceedingly difficult for Dave to distinguish between foe and friend."@en
