Watch the first footage from director Christopher Roosevelt's upcoming thriller.

On July 30th, Anchor Bay Films unleashes the biological warfare thriller The Demented on Blu-ray/DVD combo pack and DVD. From the creative minds behind I Spit on Your Grave and A Nightmare on Elm Street, The Demented is a terrifying excursion into a plague-infected world...where one moment off guard is all that keeps us from becoming them.

With a hot cast including Sarah Butler (I Spit on Your Grave), Brittney Alger (21 Jump Street), Kayla Ewell (The Vampire Diaries), Richard Kohnke (The Carrie Diaries) and Michael Welch (The Twilight Saga Franchise), The Demented will have you on the edge of your seat until the very last frame!

The Demented follows six college friends as they meet up for a carefree weekend in a beautiful rural home. A terrorist missile attack in a nearby town infects much of the townspeople with a deadly virus that induces rabies-like symptoms...with devastating consequences. Ravenous and fast, the infected townspeople turn their sights on the vacation home where the friends are gathered...and are now barricaded. How long can they hide? Even with the infected "sleeping" in the streets, can they make their escape? If so, to what?
