En cyberterrorist går til angreb på USA's infrastruktur. Alle vitale computersystemer begynder at lukke ned, og snart er landet på randen af kaos. Det er op til John McClane at bremse den gådefulde terrorist. Der venter ham lidt af en opgave, for McClane er verdens mest analoge strømer. Han ved intet om computere, men nogle gange kræver digitale problemer analoge løsninger.
