Like father. Like son. Like hell!

John McClane travels to Russia to help out his seemingly wayward son, Jack, only to discover that Jack is a CIA operative working to prevent a nuclear-weapons heist, causing the father and son to team up against underworld forces. Since the first Die Hard in 1988, John McClane has found himself in the wrong place at the wrong time, with the skills and attitude to always be the last man standing, making him enemy #1 for terrorists the world over. Now, McClane faces his greatest challenge ever, this time on an international stage, when his estranged son Jack is caught up in the daring prison escape of a rogue Russian leader, and father and son McClane must work together to keep each other alive and keep the world safe for democracy.
