The Caretaker (2008)

When a group of recent high school graduates looks to a local cemetery to ease their boredom, they are unpleasantly surprised when they run into the caretaker. George is a slow-witted small town man and the second generation to take care of the family cemetery, and when the group of unruly teens is disrespectful to his kin, George carries on another family tradition. Only Laura, one of the teens and a distant relative of George, seems to care about George's plight. But will it be enough to save her?
