Doctor Who: Dalek War

In Frontier in Space, The TARDIS comes under attack by Draconians whose empire currently rivals Earth's for control of the galaxy. But soon, the Doctor (Jon Pertwee) and Jo (Katy Manning) discover the attackers are really Ogrons. In Planet of the Daleks, the Doctor has fallen into a coma in a hostile jungle on the planet Spiridon. Jo’s search for help finds her hiding aboard the Thals’ crashed spaceship while they race to the Doctor's aid. Extras include audio commentaries and featurettes.

Frontier in Space
The TARDIS arrives in the year 2540 on board an Earth spaceship, which then comes under attack. The crew perceive the Doctor, Jo and the attackers as Draconians, whose empire currently rivals Earth's for control of the galaxy. The Doctor and Jo, however, see that the attackers are really Ogrons.
The Ogrons stun everyone on board and steal the ship's cargo - including the TARDIS. Accused by the Earth authorities of spying for the Draconians, the Doctor is sent to a penal colony on the Moon while Jo is placed in the custody of a Commissioner from Sirius 4 - actually the Master. The Master rescues the Doctor and locks him and Jo up aboard a stolen police spaceship.
Once in flight, the ship is intercepted by the Draconians. Taken to Draconia, the Doctor is able to convince the Emperor of the Master's scheme to provoke a war using the Ogrons and a hypnotic device that makes those affected see whatever they most fear.
Jo is recaptured by the Master and taken to the Ogrons' home planet, where he also has the Doctor's TARDIS. The Doctor follows with General Williams - an emissary from the President of Earth - and a Draconian Prince. Behind the Master's plot are the Daleks, who want a war to break out so that they can invade in the aftermath. The Doctor and his party are placed in the Master's custody as the Daleks leave to prepare their forces, but they manage to escape.
Williams and the Draconian Prince depart to warn their respective peoples of the Daleks' intentions. The Doctor, though, is injured in the confusion. Jo helps him into the TARDIS, where he sends a telepathic message to the Time Lords...

Planet of the Daleks
The TARDIS materialises in a hostile jungle on the planet Spiridon. Jo sets out alone to find help for the Doctor, who has fallen into a coma. She meets a party of Thals and is left in hiding aboard their crashed spaceship while they go to the Doctor's aid. The Time Lord, now recovered, learns of their mission to destroy a party of Daleks sent here to discover the native Spiridons' secret of invisibility.
Another Thal spaceship crash-lands in the jungle, and the survivors bring news that somewhere on Spiridon there is an army of ten thousand Daleks. Jo meanwhile meets a friendly Spiridon named Wester, who cures a deadly fungus disease that she has contracted.
It transpires that the Daleks' army is frozen in suspended animation in a cavern below their base. The Doctor, with the help of the Thals, explodes a bomb in the cavern wall and thereby causes one of the planet's natural ice volcanoes to erupt, entombing the army in a torrent of liquid ice.
The newly-arrived Dalek Supreme and his aides are left stranded on Spiridon as the Thals steal their ship and the Doctor and Jo depart in the TARDIS.
