Upon inheriting an ancient house where his uncle carried on studies of the occult, museum professor Cyrus Zorba (Donald Woods) moves in with his family. The late uncle's attorney, Ben Rush (Martin Milner), tells the family that his client had hidden a fortune somewhere in the creaky mansion. When Zorba finds a pair of spectacles that enable him to see the ghosts his uncle had "captured," within days the entire family has been terrified, injured or threatened by a baker's dozen of assorted spooks.
