Doctor Who: The Collection Season 20 (Limited Packaging) Blu-Ray

ARC OF INFINITY: On Gallifrey, the Fifth Doctor's home planet, a Time Lord traitor steals the bio-data code of another Time Lord and provides it to the Renegade, a creature composed of antimatter. The High Council of the Time Lords issue a Warrant of Termination on the Doctor to ensure the Renegade can no longer bond with him.

SNAKEDANCE: The Mara returns to its planet of origin, intending to use the psychic forces of a corrupt nobleman to reconstitute its being. Ah, a follow-up to Kinda. The most pleasing thing about this story is the complexity of the plot.

MAWDRYN UNDEAD: In 1983, Vislor Turlough, a stranded alien posing as a human student, is given an offer by the Black Guardian for passage off Earth if he should kill the Fifth Doctor. Meanwhile, the Doctor, Tegan and Nyssa find the TARDIS stuck in the warp ellipse of a starliner trapped in time.

TERMINUS: Still under the malign influence of the Black Guardian, Turlough sabotages the TARDIS, placing the Doctor and his companions in grave danger. Nyssa disappears through an unstable interface with a nearby space liner, and the Doctor begins a desperate search for her aboard the ship.

ENLIGHTENMENT: The Doctor (Peter Davison) and his companions Tegan Jovanka (Janet Fielding) and Vislor Turlough (Mark Strickson) encounter a group of god-like immortals who are racing historical sailing vessels from Earth through space, crewed by humans they had plucked out of time, in an attempt to win the prize of enlightenment. Turlough is under the control of the Black Guardian (Valentine Dyall), but struggles with the Guardian's orders to kill the Doctor. Enlightenment is the third of three loosely connected serials where the Black Guardian attempts to compel Turlough to kill the Doctor.

THE KING'S DEMONS: Set in an English castle in 1215. The alien time traveller the Master (Anthony Ainley) uses the robot Kamelion to imitate King John of England as part of the Master's plot to have the real King John overthrown and thus prevent the signing of Magna Carta.


THE FIVE DOCTORS (20TH ANNIVERSARY SPECIAL): A mysterious figure begins to use a Time Scoop to bring the previous incarnations of the Doctor, some of his former companions (Susan Foreman, Sarah Jane Smith, and Brigadier Lethbridge-Stewart) and archenemies (including the Daleks and Cybermen) into the Death Zone on Gallifrey.
