Non-Weird Western horror is pretty rare, so it was nice to run across this one. A family of murdering bandits, the Harps, live in the outskirts of the Central Texas town of Springville established after the Civil War. The noble West family move a little too close, and the cowardly townspeople don't give them enough warning to protect them from being slaughtered.
Generations later, and a descendant of the sole survivor of the massacre returns to town, down on his luck and hoping to take advantage of the property he's inherited. The Harps have descendants there as well, now petty criminals with stories of their violent heritage.
