[1][2] The action begins in 1977 Michigan at a run-down farm house where a man shouts for a young woman to run as he is attacked inside.
The movie then switches to Broomfield, Michigan in 1984 where we are introduced to Adrienne who is packing up a suitcase for a weekend away with her friends after the Spring Ball.
Wesley, Tobe and Sean manage to start the bus and pick up Adrienne, Jamie and the snotty Heather along with her obnoxious boyfriend Johnnie and finally Marilyn and speed off just as the principal arrives outside bewildered by the missing vehicle.
Soon the bus runs out of gas and as they argue about what to do next Adrienne, Marilyn and Jamie go into the woods to change and are watched by a heavy breathing stranger.
The friends reach the old farm house and decide to split into smaller groups to look around for anything useful at which point, while getting intimate, Johnnie and Heather find a shrine made of human bones.
As Wesley inspects the shrine he realizes he's been told about this place and to avoid it as the previous inhabitants the Joad family turned feral and began cannibalising anyone who stumbled upon their land.
They find Tobe hung up on the barn door with barbwire in agony, in horror Adrienne runs to help him and the killer steps out and stabs her in the gut with a pickaxe, killing her.
The group retreat to the farmhouse to form a plan while the killer drags Adrienne's body to an unknown location and begins butchering her and eating her flesh.
The movie starts up again with the killer, disorientated and stumbling in the woods clutching his bloodied head, although he seems to enjoy the taste of his own blood.
