The Doctor revisits the Himalayas because he wants to return an ancient relic he was given many centuries ago. On arriving however, the Doctor is blamed for a series of brutal murders in the area.

The TARDIS narrowly avoids becoming engulfed in a cobwebby substance in space. It arrives in the London Underground railway system, the tunnels of which are being overrun by the web and by the Great Intelligence's robot Yeti.

This documentary discusses a mysterious priest named Berenger Sauniere who allegedly discovered a secret treasure in his church at Rennes-le-Chateau in southern France. The program takes a fanciful journey as to whether the treasure existed and what might have been its source. It also seeks to connect Sauniere with the mythological "secret society" known as the Priory of Sion. The 1982 book Holy Blood, Holy Grail and Dan Brown's 2003 novel The Da Vinci code are both inspired by the Rennes-le-Chateau myth.

First of a trilogy of documentaries with The Priest, the Painter and the Devil (1974) and The Shadow of the Templars (1979).

For Henry Lincoln six years have passed since he completed The Priest, the Painter and the Devil. That strange story of an obscure French priest who was led to immense wealth by ancient parchments has drawn Henry Lincoln deep into a mysterious historical underworld. In France, England and Jerusalem, he has unearthed a strange story of secret societies and a medieval ecclesiastical mania which began at the time of the Crusades and which seems to have conceived and reared to maturity the enigmatic Order of Knights Templar. Henry Lincoln's story is not to be found in the history books. At its heart is the enduring French legend of Le Roi Perdu - The Lost King - and a secret linked with heresy, astrology, alchemy and an esoteric society which has survived in the shadows of history for 1,000 years.
