When Nathan Palmer and Jeff Morgan take up bare-knuckle boxing they soon regret their decision.
With the result of the fight having been decided beforehand, they find themselves running from the aggrieved Sheriff Armstrong Beck and the even more aggrieved townsfolk of Lone Gulch. They seek to make amends, but that leads to them taking part in another fight and this is one where the stakes will be as high as they can get.
Unbeknown to them they have become embroiled in a secret world where rich men pay not to watch boxers fight, but to watch them fight to the death.
As this is a dark secret these powerful men will go to any lengths to protect, Nathan and Jeff will need to do more than just fight with their fists if they are ever to get out of Lone Gulch alive.
