Four must die to protect what is his!

Two real estate agents sell a strip of land where a hermit lives. While they look over the property for the last time, the hermit uses black magic to try to stop them, as well as a pair of cops and the land's new owner after they show up. There's animated vines, giant webs, being roasted over a fire pit and an attempt at a human sacrifice to the Elemental gods of Earth, Air, Fire, and Water.
