The Westons (and Charley) travel to England to their ancestral home Weston Castle, where Harry is to receive the Sword of Weston in a ceremony. Unfortunately he gets locked in a dungeon after following a secret passage. Meanwhile back home, Laverne tries to teach Dreyfuss to ride a skateboard. Richard Mulligan plays three roles in this episode: the usual Harry, a butler named Basil, and a relative Baroness Daphne Weston.
