A waltz is cut short. Ava discloses how far she’s fallen, and how difficult she finds caring for her son.

Paul is curious about why he and his mother don’t have a car, and Ava explains it’s because they’re poor. Paul again asks why that’s so, and Ava states it’s because his father has no luck. Paul announces that he is lucky.

Paul creeps upstairs and rides his rocking horse, asking it to take him to where luck is. He rides faster and faster and at the peak, shouts a name: Daffodil.

Uncle Oscar enters, having heard the noise, and asks Paul what’s going on. Paul reveals his secret: the rocking horse is lucky, and tells him the names of race horses. Oscar calls in Paul’s caretaker, Bassett, who admits that Paul tells him the names of winning race horses. The three head to the races to prove it.

Paul is nearly overwhelmed by the noise, but manages. Oscar and Bassett place their bets on Daffodil. Bassett takes the role of a race announcer, and the three watch Paul’s prediction come true. The three sing of how this will change everything.

Paul tells Oscar he hopes the winnings will stop the house from singing. Paul hears “her” sing of how there’s never enough, how there must be more. He makes Oscar promise not to tell his mother about where the money comes from; it might ruin the luck. Oscar tells him to never stop riding.

Paul asks his mother why she always sings sad songs and if she knows anything happier. Ava rebukes him. She expresses profound regret for the stupidity and vanity of her youth. The world only smiles for the young, she says. Paul hopes she’ll smile for her birthday tomorrow, but she does not. At her birthday party, Oscar gives her the winnings from the race, but her response is dry: it’s not enough.

The predictions keep coming true, and the money keeps coming. The money gets spent, and Paul keeps riding. All the while the house is getting filled with finery. But it keeps singing. There must be more, but Paul’s luck falters as his energy wanes.

The last ride has left Paul gravely ill. Oscar and Bassett tell him they bet it all, and they’re set for life. Paul asks his mother if she’ll finally be happy- finally smile. She does, but as they leave his room to celebrate, Paul hears the house whisper. There must be more. Paul is desperate, and crawls to his rocking horse for more luck, more money. He tries to ride, fails, makes one final call for his mother, and dies alone.

Ava bemoans Paul's lack of understanding, and her need for luxury.
