Museum curator Tobin Wyler heads to London to get some answers from his former flame and suspected art thief Pierce Worthington following the theft -- and subsequent return -- of the emerald called the Green Sorrow from his exhibition in New York. He understands why Pierce and his family steal things, but it's going to take more than understanding to make a future with Pierce. When the National Gallery hires Pierce's security firm to help thwart a robbery, Tobin joins the team, but soon finds what he suspects to be a fake hanging on the walls of the world-renowned museum. He and Pierce follow the forgery's trail and find more than they bargain for when they try to uncover the truth. Can Tobin and Pierce's relationship survive what they discover?
