Spring Break is here for the small college town of McLeansville, Wisconsin. With nothing else to do, a small group of students venture out to the historical murder sites of Haunchyville, where legends claim small creatures used to roam and hunt. And kill.

Little do they know that when they head back to campus, they bring along a pack of tiny stowaways with bottomless appetites and mouths packed full of sharp teeth ready to munch on human flesh.

The Haunchies are still alive, and they're out of control!
