Things aren’t going well for John McClane: his marriage is breaking up, he’s been suspended from the force and now the brother of Hans Gruber, the German terrorist he threw off a building a few years back, is threatening to blow up a school if McClane doesn’t run around the city solving his demeaning and dangerous puzzles. With the help of Zeus, a Harlem electrician, McClane discovers Gruber’s plot to distract the NYPD while he clears the federal bank of billions of dollars of gold.
