SPOILERS: In this the third and final part of the mini-series the story moves ahead several years, with Cal and Aron as teenagers. They are opposites: Aron is virtuous and dutiful, Cal wild and rebellious. In a parallel situation to Adam and Charles, Cal believes that Adam favors Aron, and acts out to get his father's attention. Cal learns that Kate is still alive and goes to see her. Cal's goodness and professed love for his father makes Kate uncomfortable, and she spitefully tells him that he is just like her. Cal replies that she is merely afraid, and leaves. On his way out, she tells him not to tell Aron. When Adam goes nearly bankrupt after a bad investment, Cal resolves to prove his worth by making the money back. He goes into business with Samuel Hamilton's son Will growing beans, with the expectation that crop prices will skyrocket when the U.S. declares war on Germany. Their plan succeeds and they make a huge profit, which Cal proudly presents to his father. To his dismay, however, Adam rejects the gift as "dirty money". Cal lashes out by taking Aron to see Kate at the whorehouse and introducing her as their mother; Aron is horrified, and runs away to enlist in the war. Racked with guilt, Cal burns the money he made from the investment. Kate, meanwhile, loses her mind. In the following months, Cal and Aron's girlfriend Abra fall in love. Tragedy strikes, however: Adam receives a telegram saying that Aron has been killed in battle, and suffers a debilitating stroke. Cal feels responsible, and confesses to Adam what he did. Lee tells the dying Adam that he must give his only remaining son his blessing so he can live a good life. With his last ounce of strength, Adam says one last word to Cal: "Timshel". Only this last segment shares a similar plot with the 1955 James Dean version that only used the end of the book.
