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