Although their own father, bank Charles, refuses them a loan to start a novelty American toys company to rival the established German import, the brothers A.C. and Frank succeed, especially with constructive and educational products. When the US gets dragged into Word War I, Frank enlists and Woodrow Wilson's government recruits A.C. as consultant to convert factories like theirs for the war effort. Yet his gifted preteen son, whose schoolmates meanly turned on the 'Christmas killer's kid', ends up convincing him to refuse canceling Christmas and even resume toy production.
