Long Fire: Part 1 - This man is solitary, cold, methodical, and unencumbered by scruples or regrets. The killer waits in the shadows, watching for his next target. However the longer he waits, the more he thinks he's losing his mind, if not his cool. A brutal, bloody, and stylish noir story of a professional assassin lost in a world without a moral compass.
