When guitarist Dean Thibodeaux tries to score weed the night before his band goes on tour, the deal ends in a brutal attack he wasn't supposed to survive. Stiff, bloody, sore-but alive-he boards the bus with his band, determined to keep the one thing that's important in his life on track. Carl Delacroix failed his sister. And in the dead of night, with a gun in his waistband and nothing left to lose, he fails her again: his hesitation lets her killer get away. Short on sleep, short on cash, and determined not to make a trifecta out of his failure, he takes off after her attacker. And finds himself following a tour bus. Dean Thibodeaux is sick. He's changing. And the thing that caused it is coming after him, intent on fixing its mistake. One man is hunting evil. The other is becoming it. Salvation lies in the crossing of their paths.
