A highly intelligent government expert who is badly maimed in a nuclear accident is given another chance, and a new purpose, when his scientist fiance invents a realisticly human-looking mechanical exo-skeleton just for him. She's given him a new body, in fact many new bodies of different physical appearances and enhanced strength to overcome his handicaps, but she can't give him the courage to overcome the emotional scars. He must learn to do that himself. Now a terrorist organization threatens to set off a nuke if their demands are not met. Can our newly-empowered hero overcome his pain and use his wits and new mechanical body to beat the clock and save the lives of thousands?
