After serving an 18-year sentence for multiple murders, Cain plans to settle down as a rancher upon his release from jail. He has no intention of ever picking up a pistol again. But the ghosts of his past continue to stalk him; not only does no one want to hire him, but a few nefarious individuals also want to exact revenge on him. As a result, he has little choice but to take up the showman Ruffalo's invitation to participate in his traveling shooting show as "Killer Cain." However, after 18 years of not practicing his shooting, even Ruffalo's young helper Billy is able to shoot better than Cain.
