As Alison spends more and more time with Lucy, she has to have a frank talk with Kitty about her feelings of jealousy. The Captain offers Kitty a shoulder to cry on, but in doing so unearths an inconsistency that needs explaining. Luckily Lady Button has recently become a sleuthing expert, so the Captain recruits her to help uncover the truth. Meanwhile, Pat leads Mary and Robin in an improvisation class with varying success, and Thomas is determined to show off his football skills to impress Alison, but Humphrey's Head is not best pleased that he will have to "play ball" — literally. While Julian helps (and hinders) Mike to film a promo video for the house using a fancy yet unruly drone camera, the Captain, Kitty and Lady Button work together with the other ghosts to solve the unfolding mystery they've discovered before it's too late and all at Button House is lost.
