The town of Lone Ridge was a lawless hell-hole until the ruthless Nyle King eliminated all the gunslingers. Now Nyle controls the town and everyone who opposes him ends up dead, so US Marshal Caine tasks his deputy Gabriel Flynn with bringing Nyle to justice. Gabriel goes to Lone Ridge, but only because he's searching for the outlaw who killed his brother, and believes Nyle may be the key to finding him. But Nyle claims that the recent deaths in town aren't his work and that someone is trying to frame him. No longer knowing who to trust, the only thing Gabriel can be sure of is that hard lead alone will unmask the guilty and let him finally have his vengeance.
