A family wakes up one morning and realizes that they are trapped in their home by a mysterious and unbreakable steel wall. An intense heat comes over the house as well. The TV reception has been replaced by some sort of emergency signal for which the symbol is a lightning bolt (which is also the symbol on all their clothes and food products as well as their car). They begin losing feeling in their bodies and losing their memories as well. Soon enough, they can not remember any life at all outside the house. All this time, a green blob has been forming in another room, slowly stalking the family. Another great surprise ending to another great episode of this anthology series.
As an old church is being torn down, one of the workers is mysteriously strangled by the power cord of his jackhammer as he tries to penetrate one of the walls. After a brief flashback, we find out that the leader of a devil cult had himself and a traitor to his cult walled up behind that very wall in the church. Back to modern times, a woman representing a group of preservationists wants to stop the destruction of the church because she feels there are strong supernatural forces within that should not be unleashed. The strange murders inside the church continue.
