Season Overview

The special task force is adrift after their epic loss to Darker, the mastermind behind series of high profile vigilante killings. With their captain on the run for murder and them no closer to catching Darker, the team switches gear and investigates a decades-old hostage case. In those dusty old files, they discover Darker's real identity and a possible police coverup, but establishing the wrongdoer and the aggrieved party proven more difficult than it seemed. The team must determine the true culprit before Darker does, lest he kills his way through the suspect list.
