Arthur Candlewick spends three days in a disused mine shaft with only his son’s drug stash, a book on the concept of ‘effective altruism’ and a bottle of medium-priced Bordeaux for company. When Arthur emerges, he has decided to sell the family timber business and give away his wealth to charity. His family think he has lost his mind.

His university-bound daughter, Evangeline, wants to change the world but perhaps not at the cost of her own privileged life. His son, Emil, good at maths and not much else, becomes more distant than ever. And his wife, Yara, just wants the doctor to run another brain scan on her husband.
