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 The TV reception has been replaced by some sort of emergency signal for which the symbol is a lightning bolt (which is also the symbol on all their clothes and food products as well as their car).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.
