One year after his heroics in Los Angeles, John McClane is an off-duty cop who is the wrong guy in the wrong place at the wrong time. On a snowy Christmas Eve, as he waits for his wife's plane to land at Washington Dulles International Airport, terrorists take over the air traffic control system in a plot to free a South American army general and drug smuggler being flown into the US to face drug charges. It's now up to McClane to take on the terrorists, while coping with an inept airport police chief, an uncooperative anti-terrorist squad, and the life of his wife and everyone else trapped in planes circling overhead.

NYPD cop John McClane's plan to reconcile with his estranged wife is thrown for a serious loop when, minutes after he arrives at her office, the entire building is overtaken by a group of terrorists. With little help from the LAPD, wisecracking McClane sets out to single-handedly rescue the hostages and bring the bad guys down.

Nolan Grayson (Omni-Man) is unquestionably the strongest being on our planet; he is also our most spirited protector, having saved the planet from untold calamity. His son Mark, wants nothing more than to follow in his footsteps. But there's something sinister afoot and Omni-man may not be what he appears. Which may prove even too much for the Guardians of the Globe.
