A visionary named Marvin Glass oversees the creation of many of the most iconic toys of the 20th Century. From chattering teeth to a legendary game based on a mouse trap, Glass pushes the boundaries of what a toy can be, and inspires generations. From his windowless fortress in Chicago, Glass reinvents the way toys are imagined and invented...building himself a toy empire. But his tyrannical style will set him on a collision course with his own designers--in a clash for control of the most important element of the toy universe: ideas.
