On his way home to celebrate his third wedding anniversary, Thomas Prescott is forced into an unexpected detour after picking up a hitchhiker. Upon dropping the man at what is supposedly the home of the hitchhiker's doctor, Prescott finds himself thanked with an explosive device clamped to his wrist and not much time to remove it before it detonates. The hitchhiker informs his confused victim that the key is hidden in his office and instructs him to leave the device in a file cabinet once it has been removed. Racing against both time and the police, Prescott does as he's told, but he's trapped in an elevator while fleeing the now-burning building. International Rescue has been monitoring the happenings and decides that now is the time to spring into action. But have they sat on the sidelines too long? Will they arrive in time to pull Prescott from the bottom of the elevator shaft in which he's trapped, or will the fire prove too much even for International Rescue's advanced equipment? Adding to their troubles, will they learn why both man and building were targeted in the first place before the criminals can strike again? After plunging to the bottom of the burning elevator shaft, the man, though injured, is eventually saved by International Rescue. When it's discovered that the explosion targeted government files on gang activity, the FBI is called in, and International Rescue removes itself from the case -- for now. When a British agent named Southern infiltrates the gang responsible for the blast, he and two other men are dispatched to a plutonium storage facility with a familiar calling card -- explosives attached to their wrists. Once inside the heavily fortified building, Southern turns on his companions in hopes of capturing the operation's ringleader, but is himself captured by one of the facility's robot guards and locked inside with the bombs. Can International Rescue save the agent and get to the explosives before half of England is destroyed? And will the gang again manage to escape, free to continue its destruction?moreless
