Troll 2

Joshua and his family decide to do a city/country family exchange, landing themselves in the peaceful town of Nilbog. Once there, Joshua's dead grandfather returns to warn him of the evils of Nilbog and tries to get him to convince his family to leave. His parents and sister ignore him. Joshua learns that the town's inhabitants are actually goblins and that their mission is to get outsiders to eat their goblin food, turning them into trees, where they can be eaten and devoured (the goblins are vegetarians). He must work with the ghost of his grandfather to rid the town of its goblins and restore peace to Nilbog. (official distributor synopsis)
