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.

Dalchimski flees to the U.S. and starts phoning these agents who perform sabotage acts against military targets.

A renegade USAF general, Lawrence Dell, escapes from a military prison and takes over an ICBM silo near Montana and threatens to provoke World War 3 unless the President reveals details of a secret meeting held just after the start of the Vietnam War between Dell and the then President's most trusted advisors.
