The TARDIS is drawn of course and materialises in a void, and the Doctor identifies the cause as the Mandragora Helix. Unbeknown to either the Doctor or Sarah the TARDIS dematerialises with a portion of the Mandragora Helix.
The Mandragora Helix draws the TARDIS to 15th century San Martino. After the Doctor and Sarah have left the TARDIS the Mandragora energy leaves, and causes a series of deaths in its wake before eventually allying itself with the leader of a cult.
Heironymous, leader of the cult and astrologer, is being used by Count Frederico to invent false prophecies in a plan to usurp his nephew, Guiliano, who's accession to Dukedom is to be celebrated with a celebratory Masque.
The Mandragora Helix, controlling Hieronymous, plans to kill the nobles invited to the masque and plunge Earth back into the Dark Ages. The Doctor confronts Hieronymous in the underground Brethren temple and manages to draw off all the Mandragora energy before Sarah is sacrificed.
When Sarah asks if that is the end the Doctor says that the Mandragora's constellation would be in a position to act in around five hundred years time - the end of the twentieth century.
