Marge and Homer Simpson (voices of Julie Kavner and Dan Castellaneta) want to celebrate their wedding anniversary with a romantic night on the town, but circumstances force them to bring the kids along, and the evening leads them to the unfortunate conclusion the spark has gone out of their marriage.

Marge and Homer discover getting intimate outside the home gives them the thrills they've been missing, but when they return to the miniature golf course they used to visit as teenagers, their assignation inside a ball baffle shaped like a castle goes terribly wrong. Meanwhile, while playing with a metal detector, Bart (voice of Nancy Cartwright) and Lisa (voice of Yeardley Smith) discover a long-buried film can which hold a remarkable surprise -- an alternate ending to the Hollywood classic Casablanca.
