Die Hard - 1988

On Christmas Eve, Detective John McClane of the New York City Police Department arrives in Los Angeles to reconcile with his estranged wife, Holly Gennaro-McClane. McClane is driven to the Nakatomi Plaza building for a company Christmas party by a limo driver named Argyle. The party is disrupted by the arrival of twelve armed men led by Hans Gruber.

They cut the telephone lines and seal the building doors, trapping Argyle and the limo inside the parking garage and replacing the building guard with one of their own men. Hans and his group secure the party goers as hostages, but McClane manages to slip, barefoot, into a stairwell.

Gruber portrays himself to the police as a terrorist, but they are actually trying to steal $640 million in bearer bonds from the Nakatomi vault (Though it is later revealed that Gruber actually was a terrorist having gone rogue). When Nakatomi executive Joseph Takagi refuses to reveal the code for one of the vault's seven locks, Gruber executes him. Gruber orders Theo (Clarence Gilyard), the technical member of his team to break through the locks on the vault. Theo reminds Hans that the final lock is powered by circuits that cannot be cut locally...
