Young Britisher Don Wallace (Finn Cole) regretted how his nouveau riche family packed him off to the elite boarding school called Slaughterhouse. He'd soon have a lot worse than sadistic upperclassmen to have to deal with, as the fracking operations that the grasping headmaster (Michael Sheen) allowed on the grounds have unleashed a horde of bloodthirsty subterranean creatures! Horror farce co-stars Asa Butterfield, Hermione Corfield, Margot Robbie, and co-producers Simon Pegg and Nick Frost.
