Framed for setting fire to a warehouse containing the famous Nathan Claver art collection, Claude Demay (Robert H. Harris) is released from prison after six years. With vengenace on his mind, Claude plans to use a forgery of a "lost" Panamaker tapestry to prove that Leonard Voss (John Holland) is the real culprit, and that the Claver collection, allegedly destroyed in the fire, still exists. Unfortunately, Voss is murdered, and it looks like Claude is going to be railroaded back behind bars for keeps unless Perry Mason (Raymond Burr) can prove him innocent. Veteran movie leading man Conrad Nagel appears as a dapper art connoisseur, who may know more than he is letting on. ~ Hal Erickson, Rovi
