I saw half of this movie or episode when I was a kid in the early 80s (since I never watched the ending I don’t know its length).
This family of three members, father, mother and young kid (like 10 years old) wake up one day and their entire house is covered by an iron wall. They try opening all doors and windows, but all face this mysterious wall. The phone is not working, and the TV only shows a weird logo or sign.
This iron wall is a couple feet away from the house. One of the things I recall is that, despite the father and mother's frenetic attempts to figure out what's going on and find a weak spot in the wall, the kid tries to go out to play, getting trapped between the house exterior wall and the iron wall. His parents had to talk him into calmness and then convince him to walk back to the house (none of the adults could fit in the space between walls).
Last thing I saw is that the father takes an axe and goes to the attic, thinking that the iron wall might be weaker and breakable there. As he is climbing the ladder we see a tattoo in his arm, that is actually the same logo that is being mysteriously displayed on the TV. I would say that this logo looked like a secret society sigil, but maybe this memory has been "corrupted" in all these years, so maybe is not a fact to take into account.
I don’t know if it was a movie, an episode of a series or what. Anything that could lead to identifying this story or how it ended would be much appreciated.
