Ok this is a long shot and I really can't remember much, I watched this as a kid and have always wanted to watch it again.
It's a 80's horror kinda style movie, it has to do with 3 kids and a old house that I think is going to be blown up or something. The house is haunted by the rich x owner that went missing. Well he sealed himself by making a brick wall around him in the basement with lots of money and bonds and he now haunts the house.
I remember my parents got mad I was watching it since theres lots of swearing.
If anyone has any ideas please let me know, I have been wanting to see it again for old times sake.
