A successful banker, Anthony P. Kirby, has just returned from Washington, D.C., where he was effectively granted a government-sanctioned munitions monopoly, which will make him very rich. He intends to buy up a 12-block radius around a competitor's factory to put him out of business, but there is one house that is a holdout to selling. Kirby instructs his real estate broker, John Blakely, to offer a huge sum for the house, and if that is not accepted, to cause trouble for the family. Meanwhile Grandpa Vanderhof convinces a banker named Poppins to pursue his dream of making animated toys.
