Sarah and K9 have joined Mike Yates' psychical investigation group. Sarah intends to do a story on their investigations of an old ballroom. She meets the members of the group and helps them set up for their investigations. While they are separated, someone approaches K9 and shuts him down. That night they break up into groups and check the equipment. In the main hall, Peter notices that K9 isn't working and offers to fix him. Sarah enters the room with the music and finds several Victorian era couples dancing, only they are moving backwards.
