At the height of the industrial age, as America's cities go vertical for the first time, a Yale educated medical doctor and Olympic gold medalist turns his attention to toys. Leaving his profitable magic business behind, he goes all in on his revolutionary steel building toy that will inspire generations of Americans to build bigger. Creating the first-ever national ad campaign for a toy, he'll go head-to-head with a British rival who sells a remarkably similar building kit. But after decades at the top, a struggling Danish Carpenter emerges, whose passion for innovation leads him to a new building material--plastic. With it he'll create the biggest toy empire the world has ever seen.
