It's a scenario right out of a science fiction movie. What if in the future the Pentagon - the world's largest office building - had to be moved, while operating at full-capacity? That's 3.7 million square feet of office space and nearly a million tons of weight. Could it be done? One Mega Mover theorist lays out his plan for this extraordinary move. Then these same principles are put to the test when two thriving businesses -- a general store and a funeral home - must be moved with all its contents inside. For the general store, that means moving priceless antiques. For the funeral home, it's keeping caskets and embalming equipment from being destroyed. Will it be celebration or sorrow for the owners who put their trust in Mega Movers?
