Good-natured astronomer Sam is devastated when the love of his life leaves him for a suave Frenchman. He therefore does what every other normal dumpee would do — go to New York and set up home in the abandoned building opposite his ex-girlfriend's apartment, wait until she decides to leave her current lover, and then win her back.
New York detective John McClane is back and kicking bad-guy butt in the third installment of this action-packed series, which finds him teaming with civilian Zeus Carver to prevent the loss of innocent lives. McClane thought he'd seen it all, until a genius named Simon engages McClane, his new "partner" -- and his beloved city -- in a deadly game that demands their concentration.
