Bruce Willis returns as John McClane, the wisecracking, old-school New York cop. This time he's up against a group of terrorists threatening to hack into the US computer infrastructure.
When the villains crash the stock market, sending the economy into meltdown and causing panic on Wall Street, McClane turns to young hacker Matt Farrell (Justin Long). Farrell's wanted by the FBI, but he's also the only man who can help figure out the cyber criminals' next move.
The terrorists respond by kidnapping McClane's daughter Lucy (Mary Elizabeth Winstead) and so it's time for the anxious father to load up his ammo clips and go get the bad guys.
In English, with some French and Italian with English subtitles.
