After his latest bout, against young up-and-comer Cassius Clay, Mountain take a serious beating and the doctor refuses to certify Mountain for future fights. Afterward, Maish is confronted by "Ma" Greeny and her thugs, who threaten his life if he fails to repay them for the losses they incurred, based upon the sure thing bet (he urged them to wager upon) that Mountain would go down in a certain round of the match. Maish's deal with them had been that they should deduct from their winnings (due to their betting against Mountain, as Maish had advised them to). The vast sums of losses that Maish's betting (and losing) had run up with them.
Meanwhile, Mountain struggles to find a job and visits an employment agency, where he meets Grace Miller. Grace is initially standoffish but quickly becomes sympathetic to Mountain, and says she'll be in touch. Later, Grace meets with Mountain to tell him of an opening for a counselor position at a children's camp, which interests Mountain. The two bond over a drink and Mountain shares stories of his time in the ring.
