Back in the manor, Tegan and Adric have been placed in a locked room. While Nyssa heads back to the TARDIS to work on the sonic booster, the Doctor and Mace decide to question the local miller—who appears to be able to come and go from the manor with ease. Tegan and Adric eventually escape and head up into the manor proper. Adric succeeds in jumping out a window before Tegan is recaptured by the android. Unable to solicit any response from the controlled miller, the Doctor and Mace decide to join Nyssa in the TARDIS. However, just as they are leaving the mill, they are confronted by real villagers and are about to be killed for being "plague carriers".
