Anna Kosovo (Kathleen Widdoes), a friend of Ben Cartwright, has good reason to be terrified of her antagonistic immigrant husband Nick (Michael Pataki). Trapped in her own house by her husband, Anna-and her young son-must rely upon Ben to rescue them. Written by Preston Wood and Karl Tunberg, this episode is climaxed by a prolonged and tension-filled gunfight. "Frenzy" first aired on January 30, 1972-coincidentally just before the release of the otherwise unrelated Alfred Hitchcock theatrical feature Frenzy. ~ Hal Erickson, Rovi
