Bruce Willis reprises his role of John McClane, everyday NY cop with a knack for being in the wrong place at the wrong time, in this action sequel. Set in Washington DC, this fourth instalment of the franchise finds McClane asked to bring in computer hacker Matt Farrell (Justin Long) for questioning. In transit, events overtake them as they witness a full-scale cyberattack on the country's infrastructure led by mystery attacker Thomas Gabriel (Timothy Olyphant), who plans to systematically shut down or destroy the nation's major networks over three days. With time running out, McClane and his hacker friend have to stop the mastermind before it's too late.
