We have an exclusive clip from the apocalyptic horror-thriller Hellacious Acres: The Case of John Glass, which debuts on DVD April 3. Navin Pratap stars as John Glass, who awakens to a nearly uninhabitable Earth which has been destroyed by an alien invasion. You can take a look at these extraterrestrials stalking another victim in our exclusive scene.

A man suffering from amnesia wakes up in a desolate barn from a cryogenic freezer to be informed that the planet has been devastated by a world war and reduced to little habitability by a subsequent alien invasion. He is thrown into a military mission to help reestablish a livable atmosphere for what's left of humanity. Soon enough he encounters more than he bargained for: aliens, crazy survivors, inadequate equipment and a pretty unhealthy dose of bad luck. Jam-packed with visual inventions and plot twists, this movie offers a dark and humorous take on the post-apocalyptic genre.
