Jon Finch, Alec McCowen and Barry Foster star in this morbid blend of horror and wit-the first Hitchcock film to earn an 'R' rating. The Necktie Murderer has the London Police on red alert, and an innocent man is on a desperate quest to find the real serial rapist-murderer and clear his own name. Alternating heart-pounding tension with distinctive Hitchcock humor, Frenzy marked the Master of Suspense's return to his native England after almost twenty years.
