Based on a the true story. At the age of 22, Eggers became both an orphan and a ‘single mother’ when his parents died within five months of one another of unrelated cancers. In the ensuing sibling division of labour, Dave is appointed unofficial guardian of his 8-year-old brother, Christopher. The two live together in semi-squalor, decaying food and sports equipment scattered about, while Eggers worries obsessively about child-welfare authorities, molesting babysitters, and his own health. His child-rearing strategy swings between making his brother’s upbringing manically fun and performing bizarre developmental experiments on him.
