While Darrin is away, Samantha stops Tabitha from witchcraft and argues with Endora about it. Then Larry Tate invites Samantha to dinner with the Bakers, hoping she can persuade Mr. Baker to modernize his firm's package. When Samantha protests she has no baby sitter, Louise insists on sending over her Aunt Emma. She arrives at the Stephens with a ouija board, hoping to contact her fiancée, Mr. Henderson, in the next world. At the Tates, Mr. Baker refuses to make any change in his Uncle Willie's business. As Aunt Emma works on the ouija board, Tabitha floats toys around. When a rocking horse goes by, Aunt Emma, sure it's Mr. Henderson's reincarnation, phones the Tates. Samantha, sensing trouble, cuts off the call and leaves for home. The Bakers and the Tates, hearing about a ghost, troop along. At the Stephens, Aunt Emma concentrates on the rocking horse ghost of Mr. Henderson. Samantha declares she was dreaming and to prove it, twitches her to sleep. In the kitchen. Mrs. Baker sees some milk floating up to Tabitha, and demands a seance to conjure up Uncle Willie. Baker thinks it's one of Larry's tricks and cancels his account. Samantha returns to the Bakers, to persuade him to change his mind by impersonating Uncle Willie. She is stunned when the old gentlemen's ghost appears. He asks Samantha's help to keep Baker from ruining his business. When Samantha assumes Uncle Willie's form, Baker thinks it's an actor hired by Larry. Convinced by her recital of some boyish pranks, he calls Larry to plan a new image for the firm. Samantha is amused when Baker and Larry both claim credit for the change.
