Jake, Dinah, and their children take a summer trip to Amish country for a change of pace. On their first night there, the ghost of Amos Zook, an axe-wielding murderer, visits the old country home they are staying at and begins to invade their sons fragile mind. The Amish, who were keeping the evil at bay while dealing with the fallout from a massacre, will not discuss the ghost's presence with Jake and Dinah, forcing them to search for answers on their own. As secrets from the past are revealed, will Jake learn how to fight the evil before the summer solstice arrives or will his family succumb to it and follow the evil into the unknown?
