In the lobby of a high rise building, the front desk officer is watching a ballgame as he checks I.D.s. He lets a man with a large metal case through, and the man is met by another security guard who swipes a keycard and leads him into the access halls of the building. They walk past heavily armed guards, and a no-smoking sign. A computer chip is switched.A few small holes are drilled.A high-powered cutting torch is used. A submarine sinks.An off-shore oil platform catches fire.A space shuttle explodes. The building explodes spectacularly.
