After becoming a bounty hunter, Aaron Hardie never expected his life to be calm. Unlike some other bounty hunters, he is not a back-shooter but always gives the outlaws the chance to turn themselves in. Even if he knows that by choosing this tactic he is dicing with death, he always takes the risk. No matter what the cost, he uses his bravery and skills in order to fulfill his one and only dream; save enough money to buy a horse ranch and then marry his sweetheart, Jean. Little does he know that a vicious enemy has other plans for him... Will Aaron manage to take down the mysterious person who stands in the way of his happiness?
One fateful day Aaron wakes up in the middle of nowhere, facing down the burning sand with a bullet wound in the head. Although he survives this near-death experience, the bullet takes his memory. All of a sudden he has no idea who he is, nor any recollection of Jean and the future ranch. As luck would have it, he is found by some of the townspeople who take him back to Waco Flats, his hometown. However, no matter how hard he tries, he still can't remember a single thing about his past life as a gunslinger. As if that wasn't enough, he is entirely unaware that the man who wants him dead is riding by his side... Will Aaron regain his lost memory or will he be doomed to get the final blow by his secret enemy?
While Aaron is trapped in the web of his lost memories, he discovers yet another threat. The Comanches are preparing for one last, grand battle against the white man. Knowing that the days of the Comanche are drawing to a close, they want to go out in a final blaze of glory and blood. If Aaron finally escapes the shadowy man who wants him dead, will he survive the bloody battle that brings chaos to his town? Or will he fail in using his gun skills when they're most urgently needed?
