The Blunt Force Trauma teaches us a somewhat strange way of fighting. By way of an ancient duel, the participants beat with their pistols, although this time it is done in group instead of one against one.
In order not to kill each participant is wearing a bulletproof vest. The rules are to shoot the vest, losing the one that comes out of the circle they are in, something that happens because the impacts hurt despite the vest.
In these modern duels are known John and Colt, who soon have a love affair, although it seems that duels are more important to them than love.
Shortly after starting their relationship, they realize that the most important thing for both of them is to be the best in these duels, which precede love. The two want to be the best, so the clash between them is inevitable.
