A made-for-TV movie from 1991, with a perfectly played part by Don as the Sheriff of Tombstone, an old friend of Matt Dillon's. Unlike the weekly TV series on which it is based, this movie was rated R for violence.
Set in Arizona in 1880, the movie concerns the Pleasant Valley Wars between the Tewksburys and the Grahams. The Graham boys, having been taught a lesson in manners by Matt Dillon, make the mistake of stealing some of the former Marshal's cattle. While he goes after them and his daughter Beth goes after him, he gets caught up in the middle of the deadly family feud.
