The track is set during a giant house party at Curien Mansion, the home of the first and third game's antagonist Dr. Curien. In fact, it is revealed later on that the house party is celebrating the wedding of Zobio and Zobiko, the main characters of The House of the Dead who were playable in Sonic & Sega All-Stars Racing.
The race sees drivers entering the mansion and driving through places such as the cellar, a toxic river, a bouncy castle with Zobio bouncing around, a secret lab and even a concert. On the final lap, racers will take a detour that leads to a ruined wedding chapel where the wedding is finally underway, complete with Zobiko in a wedding dress. Many of the bosses from previous games appear, including Death in an evening suit, a cartoon version of The Lovers, Hangedman and Tower.
The music for the land portions of this stage is a remix of "Revenge" from House of the Dead. The music for the boat portions is a remix of "Theme of the Magician" from House of the Dead 2. In the official soundtrack, the boat portions' music is played first. The course flyover music is a remix of "Aura of Dread", the attract music from House of the Dead.
