For wanting to save a dog, Adam and Barbara Maitland go straight to the other world. Soon after, invisible occupants of their ancient home, they see it invaded by a rich and noisy New York family. Nothing to complain about until the day when this honorable family undertook to give a more urban character to the old house. Adam and Barbara, outraged, decide to dislodge the intruders. But their classic ghosts and other spells have no effect. That's when they enlisted the help of a freelance "bio-exorcist" known by the nickname Beetlejuice.
