But the dark side isn't finished with Derek. What starts off as a simple inquiry into the dealings of a shady bookie quickly descends into a battle with the shadowy unknown. Before he knows it, Derek is on the run, framed for an impossible murder. His only leverage is a strange skin belt that seems to have a life of its own, but hanging onto it might cost Derek more than just his life.
