The house that Endora zapped up across the street in her feud with Uncle Arthur has reappeared. The reason?: Endora is planning on holding a special Halloween party there, to which Samantha and Darrin are invited among her special guests. The one person not invited: Uncle Arthur. Darrin refuses to attend if only because of the house itself. Endora decides to accommodate Darrin's objection by holding the party elsewhere: at their house. Regardless, Uncle Arthur plans on crashing the party. Beyond the continuing feud between Endora and Uncle Arthur, the one thing that may dampen the mood of the party is a nosy Gladys Kravitz, who brings in what she considers the big guns in investigating the unusual goings-on at the Stephens house.
