Film
Before the movie began, Stuart was trained by Major Grant in the army. He plans to betray his country and free General Ramon Esperanza from confinement in America. This all starts when Stuart and his men take over a church and they tamper with Dulles Tower's controls and make replicates of them. When Dulles Terminal police tried to get to an antenna, Stuart retaliated by crashing and blowing up a British plane with everyone on it, much to McClane's horror. When his former mentor first met McClane, Stuart didn't know of his presense until Grant betrays the good guys for Stuart.

As the getaway plane prepares for take off, McClane gets onto the wing and battles first Grant then Stuart. When Stuart thinks he's won, he failed to see McClane cause a fuel leak in the plane. This allowed the heroic cop to light the fuel with a lighter which trails the fire to the plane. The plane is then blown up with everyone including Stuart and Esperanza on board.
