A former supercop looks for trouble in a small town. His son stockpiles a drug that stops time. Meth dealers cover their body in snakes. A killer is pursued backward through time by interdimensional time-worms. All of these stories will come to a head following the appearance of an otherworldly assassin who can swallow his victims whole.
