Mothman

In Point Pleasant, West Virginia, home to the legend of the Mothman, a group of high school seniors camp out next to a river near an old mill where the Mothman is supposedly buried under the incinerators. While scaring their friend Jamie with the Mothman's legend, the teenagers accidentally drown Jamie. The teenagers decide to cover up the accident by claiming that Jamie hit his head while jumping into the river and fake evidence by hitting his head post-mortem with a rock.
