 John McClane is a cop from New York City who is on his way to Los Angeles to see his kids and his wife Holly, who moved to LA because of a job at the Nakatomi Corporation. When he arrives at Nakatomi Plaza, he meets Holly s boss Joe Takagi and her co-worker Harry Ellis. He and Holly go into a private bathroom and get into an argument. When Holly leaves to give a speech, thirteen armed terrorists lead by Hans Gruber seize control of the building and take the occupants of the 30th floor, who are the only ones left in the building, hostage. Luckily, they missed John since he was in the bathroom. He sneaks out and witnesses Gruber kill Takagi. He goes to floor 32 and pulls the fire alarm, but the terrorists cancel the alarm and send someone up to kill John. However, he kills the terrorist and steals his machine gun. Now he has to kill the rest of the terrorists and save the hostages before the terrorists get their way.
