James and Alexander use anti-tank missiles to knock out a SWAT Greyhound armored car, but before they can finish its destruction, they are killed when their building floor is blown up by C-4 that McClane dropped. Holly's coworker Harry Ellis attempts to mediate between Hans and McClane for the return of the detonators. McClane refuses to return them, causing Gruber to murder Ellis. While checking explosives attached to the roof, Gruber is confronted by McClane. Gruber passes himself off as an escaped hostage and is given a gun by McClane. Gruber attempts to shoot McClane but finds that the gun is unloaded. Before McClane can act, Karl, Franco, and Fritz arrive. McClane kills Fritz and Franco, but is forced to flee, leaving the detonators behind.
