Die Bürgschaft centers on the farmer Mattes and the merchant Orth. At the beginning, Orth pledges to protect Mattes, who is in debt, from his creditors. Mattes pays off all his loans, and buys two sacks of grain from Orth. He discovers a large sum of money in the sacks, which he decides to keep. When Orth learns of this, he says the money is not his; the Judge is consulted,and he rules that the money be split between their children. Then their homeland, Urb, is invaded by an industrialized colonizing nation, which recognizes only the laws of money and power. Orth and Mattes are then found to be criminals and forced to serve the new government, which makes them rich. After six years elapse, War, Inflation, Famine, and Disease sweep through Urb, and the people revolt. At the final curtain, Orth offers Mattes to the mob to save his own life--the triumph of money and power.
