After the children’s tongue-lashing at school for setting off dynamite caps at recess, Morticia and Gomez enroll them at Mockridge Private School headed by their “old friend” Sam Hilliard. Headmaster Hilliard’s none too happy about having Addamses in his life again. Gomez takes this to mean he’s under too much pressure from his board of regents, so he surprises Sam by buying Mockridge Hall, changing its name to Addams Hall and having it run “as it should be run ” with courses in head-shrinking, taxidermy, do-it-yourself dentistry and demolition by dynamite.
