　　Set in the 1930s, an American with a scandalous reputation on both sides of the Atlantic must do an about-face in order to win back the woman of his dreams.

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 yakubd.cc and Woodrow Wilson's government recruits A.C. as consultant to convert factories like theirs for the war effort.
