Bit player Sherry Stewart gets miffed when director Walter Darman turns her down after she reads for a small part in his picture. She and her boy friend, Ronnie, devise a plan to lure Darman to her apartment, where she gives him a drugged drink. She tells Darman they had been intimate and blackmails him for $50,000.
