Leaving the kids at home with Endora (Agnes Moorehead), the Stephens set off on a much-needed European vacation during which Darrin (Dick Sargent) heads back in time to 16th century England to rescue Samantha (Elizabeth Montgomery) from the clutches of King Henry VIII. Following witchcraft-filled stops in Loch Ness, Pisa, Paris, London and Rome, they return home, where, after Tabitha’s magical powers threaten to make her a reluctant television star, she and her mom trade places with storybook characters Hansel and Gretel. As Endora and Cousin Serena continue stirring up trouble for Darrin at work and at home, a test ordered by the Council of Witches proves that son Adam has the power of witchcraft after all. Even though Samantha must teach both children to manage their magical abilities, she and Darrin try and keep witchcraft from upending their lives…at least too much.
