During an aimless tour of the endless depths of the TARDIS, the Doctor introduces Sarah to the ornately wood-paneled secondary control room, which duplicates the functions of the master console room. When he fires up the secondary control room’s instruments, the Doctor discovers that the TARDIS is headed for the Mandragora Helix, a spaceborne vortex of malevolent energy. Forced to the land within it briefly, the Doctor is helpless to prevent a fragment of the Helix’s energy from boarding the TARDIS. After escaping from the vortex, the Doctor is surprised when the TARDIS brings them to late 1600s Italy, where Sarah is promptly kidnapped by a band of hooded figures. While trying to find her, the Doctor realizes that the Mandragora Helix has come to Earth. The local Duke has died, and his young, idealistic son Giuliano now holds his power, though the local population is under the tyrannical thumb of the boy’s uncle, Count Federico. And Sarah is about to be sacrificed by a murderous cult which will find a great ally in the unearthly newcomer which the Doctor has unwittingly brought with him.
