An investigation into the ineffable relationship we have with art. Hidden Treasures introduces us to people who spend their days and nights surrounded by great works of art and have developed powerful connections to these singular objects. Filmed inside the Metropolitan Museum of Art in New York, featuring interviews and discussions with many of the museum's staff of curators, security guards, restorers and educators, Hidden Treasures recounts stories about the magic inherent in great works of painting, sculpture or craft.
