Boston painter Claire Roth has survived financially by painting reproductions, so when influential gallery owner Aiden Markel arrives with a bizarre proposal--her own show if she will forge a copy of a Degas, one of the pictures stolen from the Isabella Stewart Gardner Museum--she says yes. As she works, Claire and Aiden become lovers, but she doesn't tell him about her discovery that the stolen Degas is itself a copy. This knowledge is Claire's lifeline when the finished forgery is discovered, Aiden and then Claire are both arrested, and only she can save them.
