In the rural recesses of Hawaii, a pair of friends must fight an ancient evil force brought to life by an occult book that possesses a group of construction workers, turning them into murderous maniacs. Shot and edited on consumer grade equipment by twin brothers Brent and Blake Cousins, SLAUGHTER DAY is packed from start to finish with kinetic lo-fi action scenes, gonzo camerawork and a truckload of homemade gore.
