In this action-comedy, unusual circumstances find big, brawny cop John Kimble (Arnold Schwarzenegger) posing as a kindergarten teacher in order to apprehend major drug lord Cullen Crisp (Richard Tyson), as well as his ruthless accomplice and mother, Eleanor (Carroll Baker). While pretending to be a kid-friendly instructor, Kimble falls for pretty fellow teacher Joyce Palmieri (Penelope Ann Miller) as he battles both unruly children and dangerous bad guys.
New York City policeman John McClane (Bruce Willis) is visiting his estranged wife (Bonnie Bedelia) and two daughters on Christmas Eve. He joins her at a holiday party in the headquarters of the Japanese-owned business she works for. But the festivities are interrupted by a group of terrorists who take over the exclusive high-rise, and everyone in it. Very soon McClane realizes that there’s no one to save the hostages — but him.
