On Christmas Eve, New York cop John McClane (Bruce Willis) is visiting his estranged wife Holly (Bonnie Bedelia) in Los Angeles, where she works. They are attending a party at Holly's high-rise office block when terrorists, led by the suave Hans Gruber (Alan Rickman) break in, taking everyone hostage. McClane manages to evade capture, however, and sets out to rescue his wife and the other prisoners. It is not long before he is running barefoot over shattered glass (ouch!) in a sweaty vest, muttering 'Yippy kay aye' as he dispatches the baddies with bullets and a certain earthy wit.
