Art can be very valuable and, thus, eyed by people looking to acquire pieces of artwork by nefarious means to sell. This show views investigations of notable art thefts through the eyes of detectives and forensics analysts tasked with locating missing masterpieces. Each episode focuses on one infamous theft or related mystery, using archival footage and re-enactments to illustrate how the piece disappeared and -- in many cases -- was recovered. Highlights are the 1911 theft of the "Mona Lisa," a trove of treasures stolen by the Nazis, and Fabergé eggs missing since the Russian Revolution.
