Die Hard (1988)

It's Christmas Eve, and there's an employee party in progress on the 30th floor of the Nakatomi Corporation building. New York City Detective John McClane becomes the only hope for a small group of hostages, one of whom is his estranged wife, trapped in a Los Angeles high-rise office building when it is seized by a group of terrorists headed by Hans Gruber, who plan to steal the 600 million dollars locked in Nakatomi's high-tech safe.
