Michael Wolffsen has just gotten custody of his only sister’s son after she was murdered by her husband before his very eyes.
To fulfill his sister’s dying wish, Michael takes his nephew and wife and makes the journey home to his only other living relative: his estranged, eccentric (and extremely paranoid) father who is obsessed with building an unassailable compound.
Once there, Michael hopes to repair his shattered family, but instead he finds that they are all trapped inside his father’s creation when the ghost of his vengeful brother-in-law returns to wipe out the rest of the Wolffsen family.
