Here is the summary of The Goldfinch from variety.com:
Based on Donna Tartt’s Pulitzer Prize-winning book, "The Goldfinch" follows a young man named Theodore Decker who survives a terrorist bombing at an art museum — an attack that kills his mother. From there, he tumbles through a series of adventures that finds him living in Las Vegas with his deadbeat father and, later, involved in art forgeries.
