Isaac Collins are passed on to the MET. However, unbeknown to the relief, his resignation is part of an elaborate cover story to disguise the fact that he has secretly gone undercover to gather evidence against Collins. When Collins offers him the job of security manager, Okaro uses the opportunity to fool a less than alert security guard into handing over a swipe card for Collins' private office. However, just as he is on the verge of nailing Collins and locating gunman Martie Kenton, Collins susses that he has been played and decides to exact a frightening campaign of revenge on his former com-padre.
