This video reconstructs one of the world's most unusual undercover operations. Journalist Peter Watson disguised himself as an art dealer of unsavory reputation and in concert with Sotheby's, Christie's, and members of various law enforcement agencies, set himself up as the center of a sting operation. The object? To recover some of the world's stolen masterpieces of art, including a painting by Renaissance master Caravaggio. ~ Rob Ferrier, Rovi.
