The Campground(2013)

In 1980 a mother took her son to get a present on his 10th birthday. They went to an old abandoned Campground: Little Farm on the River. She took him to an old camper and asked him to step inside, once he did she reached out and grabbed a screwdriver sitting on the counter and began stabbing him over and over again. Now 30 years later a group of friends decide to go down to the campground to celebrate a birthday party, but the mood soon changes when people start turning up dead. Will the the teens be able to check out or stay at camp permanently?
