The profligate playboy son of Rufus Carnahan, a retired multimillionaire industrialist who summons Superman to his home in May 1940 and offers to pay him â€œany amountâ€ if he will only cure his son of his wastrel, decadent ways. â€œStraighten out my sonâ€™s character so that he will be a man!â€ pleads Carnahan. â€œIâ€™ll pay you any amount!â€
Soon after Superman has agreed to accept the task, Peter Carnahanâ€”a â€œweak-kneed sop and spendthriftâ€ beset by â€œhuge gambling lossesâ€â€”is convicted and sentenced to death for a murder he did not commit, but Superman produces the real murderer and stops the execution in the nick of time, prompting the grateful playboy to vow to abandon his decadent lifestyle and devote the rest of his life to helping â€œwayward underprivileged youthâ€ (Act No. 24).
