Synopsis: In the TARDIS, Ace barges into the console room trying to get the Doctor's attention. He's busy, however, trying to trace down a mysterious force that appears to be controlling the TARDIS. He heads for the secondary console room, where he remembers a (televised) encounter with the Mandragora Helix. Now very concerned, the Doctor and Ace begin to search the TARDIS for any sign of the Helix.
Notes: The second of two "pre-title" sequences for "The Mark of Mandragora".
