Pro Maksim Chmerkovskiy returns to guest judge as the celebrities and professional dancers switch partners for one week.

The eight remaining couples will perform an individual Halloween-themed routine in addition to a competitive team dance. For the team dances, the cast has been divided into two frightening teams: Team #Nightmare and Team #WhoYouGonnaCall. These two teams will compete against each other, vying for a perfectly wicked score from the judges. Actress and "Dancing with the Stars" Season 17 semi-finalist Leah Remini also returns to guest co-host alongside Tom Bergeron. At the end of the night, one couple will face elimination.
