Nope its not this movie.
It has some similiar sequences but nope.
This house is the only house there ( i guess)
Husband and Wife are living normal life, but its getting everyday worse, they start getting psychologicaly sick, the wife/mother visit a doctor.
Then the husband get crazy too, until they (i guess it was the wife) explores the cellar, the secret of the movie is this cellar.
After that everything becomes normal, i remember in the cellar, there were death bodies.
It has been a long time when i watched this movie, cant remember 100%
But ty very much for your effort
