Theodore "Theo" Decker (Ansel Elgort) was 13 years old when his mother was killed in a bombing at the Metropolitan Museum of Art. The tragedy changes the course of his life, sending him on a stirring odyssey of grief and guilt, reinvention and redemption, and even love. Through it all, he holds on to one tangible piece of hope from that terrible day... a painting of a tiny bird chained to it's perch. The Goldfinch.
