 Madge Wainwright, owner of an exclusive women s wear store, sees cheap knockoffs of designs she is selling for big bucks and complains irately to fashion house owner Wally Dunbar and chief designer Rick Stassi, who decide to scrap their previous work and create new designs with model Kitty Wynne as the focus. Madge and Rick were once an item. Wally is seeing Kitty, who also has a history with Rick. Assistant designer Lisa Ferrand wants Rick, but he spurns her. Lisa s husband, photographer and lush Bud Ferrand, shoots a series of Kitty in the new designs. Wally discusses design security with Perry Mason, who assigns the case to Paul Drake, who follows Kitty to Rick s house and finds sketches of the new designs in her car. Newspaper ads appear for a competitor with the new Dunbar designs. Rick is killed and Kitty charged with murder.
