The terrorist group, OBL-911, attacks New York City killing and wounding several hundred people, but they suffer major losses from the Joint Terrorist Task Force forcing them to go into hiding. JTTF member Harry Cassidy gets promoted to sergeant and returns to regular patrol duties now that the threat is over. With the help and love of his fiancee, Sergeant Rita Becker, Harry seeks to advance his career in the police department and re-establish ties with his daughters. After many years OBL-911 re-groups for one final assault on New York planning to kill millions using deadly poisons, nerve agents and dirty nuclear devices. The JTTF, now under the leadership of Inspector Harry Cassidy, is once again called upon to save the city, and the country, from death and destruction in one final confrontation."
