The very first crew of the TARDIS land in a petrified forest on an alien planet. Determined to explore, the Doctor leads his companions into the metal city, where they discover danger at every corner and what will become his deadliest enemy... the mutant Daleks. It's time to encounter the Daleks once again, but this time in a way you've never seen them before. Originally transmitted in December 1963 to February 1964, the seven original episodes of the first Dalek story have received a cosmic makeover, dazzlingly colourised and woven together into a 75-minute blockbuster with brand-new sound and a brand-new score created by Mark Ayres. The Daleks has been gloriously updated, whilst ensuring the original story remains as thrilling as it was in 1963.

A writer attempts to raise some cash by writing a book about the Loch Ness Monster. No publisher will take it because they all think there isn't really a monster. The writer and some of his friends make a fake monster and take photographs and then travel to Scotland to see if they can convince the locals.

Two young English women go on a cycling tour of the French countryside. When one of them goes missing, the other begins to search for her. But who can she trust?

Intercepted while travelling between Earth and the Ark, the Fourth Doctor and his companions are transported to the planet Skaro on a mission for the Time Lords — to prevent the creation 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.
