A valuable Matisse is stolen from an art museum and replaced by a forgery. Museum curator June Sinclair (Mala Powers) and her boyfriend David Lambert (Joe Maross) are suspected of the crime--and then charged with the murder of the actual thief, David's wife Lisa (Carmen Philips). Thus it is that Perry Mason (Raymond Burr) has two clients to save from the gas chamber. The huge supporting cast includes veteran radio actresses Isabel Randolph and Elvia Allman, and former B-western hero Jack Perrin. ~ Hal Erickson, Rovi
