Vengeance is the Spur (2017)

Vermijo is a character driven western and touches on some real contemporary subjects - alcohol abuse, bullying, domestic violence as well as the usual favourites seen in westerns. When their no-good brother is killed in a gunfight with a passing drifter, the sheriff and deputy of a small western town set off with a posse after the killer. But they're not interested in justice, nor even revenge. They plan to use the drifter as an example to keep the rest of the town in line. Unfortunately for them, an old man has other ideas - and when a startling secret is revealed, so does the town itself.
