John McClane (Bruce Willis) and his estranged son Jack (Jai Courtney) team up to protect a government informant in Moscow, and thwart a major crime in Chernobyl in this sequel from director John Moore (Max Payne, Behind Enemy Lines). Russian politics are in tatters when veteran detective McClane shows up in the nation's capital, and learns that his son is working undercover to protect Komarov (Sebastian Koch) -- a notorious whistleblower who some powerful people would like to see silenced. Protecting Komarov won't be easy, even for the cop who's single-handedly defeated small armies of terrorists, and the sharp-shooting son he's never known. Meanwhile, when the fearless father and son catch wind of a deadly plot unfolding in Chernobyl, they face the fight of their lives in one of the most hostile landscapes known to man. Cole Hauser and Mary Elizabeth Winstead co-star. ~ Jason Buchanan, Rovi
