The Doctor (William Hartnell), Ian (William Russell), Barbara (Jacqueline Hill) and Susan (Carol Ann Ford) find themselves stranded in Aztec times when the TARDIS is trapped in a tomb. Proclaimed a goddess by the Aztec priests, Barbara attempts to change the course of history by forbidding the human sacrifices which are part of the Aztecs' religion. It is up to the Doctor to find a way back into the tomb and recover the TARDIS, before the priest Tlotoxl (John Ringham) unmasks Barbara.

More sci-fi adventures for the gallant Timelord and his faithful chums. This time around, the TARDIS malfunctions and shrinks the Doctor (William Hartnell) so that he is just one inch tall. He then arrives on Earth and uncovers a diabolical plot by a ruthless businessman who has developed an insecticide so powerful that it will wipe out all insect life on the planet. The Doctor and his companions Barbara (Jacqueline Hill), Ian (William Russell) and Susan (Carole Ann Ford) try to put an end to these foul schemes, but that's obviously not so easy when you're no bigger than a thimble.

Compilation of a six-part story from the popular sci-fi series. The Doctor (William Hartnell), Ian, Barbara and Susan return to Earth in the year 2167 only to find that the Daleks have occupied the planet. They join the human resistance movement in an attempt to overthrow the Daleks, who are mining the core of the planet for a sinister purpose of their own. This story was remade into a film, 'Daleks - Invasion Earth 2150 AD', starring Peter Cushing as the Doctor.

Two more adventures from the Doctor Who television series. In 'The Rescue' the Doctor lands on Planet Dido in the year 2493. He finds two human survivors from a ferocious Didonian attack, and must discover the motivation behind this violence. In 'The Romans' the Doctor lands in Italy 64 A.D., but his intention to have a holiday is destroyed when he is mistakenly identified as a murderer.

An early adventure for everyone's favourite time traveller. When the TARDIS lands on the planet Marinus, the Doctor (William Hartnell), Ian, Barbara and Susan are captured by Arbitan, Keeper of the Conscience of Marinus. The Conscience is an all-powerful machine which controls the planet in an attempt to regulate crime, but it requires four missing crystals to complete its function. Otherwise, the machine could fall into the hands of the Voord, led by the evil Yartek. The TARDIS crew are thus charged by Arbitan with recovering the crystals before it is too late.
