Theo Decker, a 13-year-old New Yorker, miraculously survives an accident that kills his mother. Abandoned by his father, Theo is taken in by the family of a wealthy friend. Bewildered by his strange new home on Park Avenue, disturbed by schoolmates who don't know how to talk to him, and tormented above all by a longing for his mother, he clings to the one thing that reminds him of her: a small, mysteriously captivating painting that ultimately draws Theo into a wealthy and insular art community.
