Last Of The Dogmen (1995)

Cliched modern western with an intriguing premise and good actors. Montana bounty hunter Lewis Gates (Berenger) is recruited to nab three escaped cons but finds them dead and a Cheyenne arrow nearby. Gates does some investigating (in a library no less!) and discovers that maybe some descendants of the 1864 Sand Creek massacre are existing in the woods. He gets anthropologist Lillian Sloan (Hershey) involved, discovers a tribe of modern-day dog soldiers, and finds a very angry sheriff (Smith) on their trail. Alberta, Canada passes for Big Sky country.
