The Far Side of Jericho (2006)

Jericho. In the 1880's. Three women of the wild West, widows of an outlawed gang of brothers recently hanged, find themselves running for their lives from a corrupt posse of vigilantes, mystical Indians and a hornet's nest of villains - all are convinced that our mismatched widows hold the key to the whereabouts of their husbands' missing bank loot and a mysterious treasure.
