Classic Doctor Who

School teachers Ian and Barbara follow their student, Susan Foreman, back to her home which is just an old junk yard. There they meet an old man and suspect him of abducting Susan.

With 1963 London left behind, the teachers are amazed to find themselves on prehistoric Earth and are taken captive by a tribe of cavemen who are searching for the secret of fire.

The time travellers manage to escape the tribe but their path to the TARDIS through the forest holds dangers of its own. Meanwhile, Kal attempts to take advantage of events.

Kal has been banished from the tribe and Ian is making fire for Za in the hope that he will be grateful and will allow them to return to the TARDIS.

The travellers venture out on to the surface of a new world. Everything is dead but beyond a petrified jungle they see a huge metal city which the Doctor is determined to explore.

Looking for Barbara, the Doctor, Ian and Susan discover that they have exposed to lethal doses of radiation. The travellers are confronted by the city’s inhabitants – the Daleks!

Fearful of a Thal attack, the Daleks force Susan to trick the Thals. Realising that the Daleks are planning an ambush, the four travellers try to escape and warn the Thals.

Pretending to be a Dalek, Ian finds that that he is trapped inside the casing. The Doctor, Susan and Barbara have no choice but to abandon Ian as the real Daleks arrive and attack.

Ian and Barbara join a Thal expedition that will penetrate the Dalek city from the unguarded mountains behind it. Their journey is a dangerous one and not all will survive.

The Doctor and Susan are once again taken prisoner by the Daleks. In the mountains, Ian, Barbara and the Thals must negotiate a vast chasm to reach the city.

The Thals and the time travellers attack the Daleks from all sides as the Daleks start the countdown to release deadly doses of radiation into the atmosphere.

The TARDIS is suspended in space and the Doctor, Ian, Barbara and Susan are confused and frightened by a series of inexplicable events.

As the power of the TARDIS threatens to escape and destroy the ship, the travellers become increasingly paranoid and hostile towards each other.

The TARDIS lands on a remote island, surrounded by a sea of acid. They meet Arbitan, keeper of the Conscience of Marinus who forces the travellers to go in search of five keys.

In the city of Morphoton, the Doctor, Barbara, Ian and Susan are welcomed as honoured guests and given anything they want. But Barbara soon discovers that paradise is an illusion.

Ian and Barbara find a temple in the middle of a hostile jungle. Inside is the ailing Darrius, keeper of one of the keys. As Darrius dies he gives Ian a clue to find the key.

In a snowy wasteland, Vasor, an unscrupulous trapper, imprisons the travellers in a frozen cavern inside a mountain. There they find one of the keys frozen in a block of ice.

Arriving in the city of Millennius, Ian is put on trial for murder. The Doctor takes on the role of defence counsel and must prove Ian's innocence or he will be executed.

The Doctor solves the murder mystery and finds the final missing key. With Ian now free, the travellers return to the island only to discover that Arbitan has been murdered.

The TARDIS lands inside an Aztec temple in 15th Century Mexico and become cut off from the ship when they leave the temple to explore.

The High Priest of Sacrifice, Tlotoxl begins to doubt Barbara's claim to be the reincarnation of Yetaxa and plots to undermine her position and eliminate her friends.

The Doctor and Ian attempt to find a way back the TARDIS. Barbara attempts to distract Tlotoxl but the High Priest of Sacrifice already has plans for Susan.

Tlotoxl is preparing to make his move and have Barbara, the Doctor, Ian and Susan killed. Ian prepares for a fight to the death with the warrior, Ixta.

The TARDIS lands inside a spaceship orbiting the planet Sense-Sphere. The ship's crew are apparently dead but surprise the travellers when they abruptly return to life.

The Doctor and his companions are on board an Earth ship trapped in orbit around the Sense-Sphere when it is boarded by the Sensorites who steal the lock mechanism from the TARDIS.

The Sensorites take the Doctor, Susan, Ian and members of the spaceship crew down to the surface of the Sense-Sphere. There the Doctor learns about a previous Earth expedition...

On the Sense-Sphere, Ian has succumbed to the deadly illness that is spreading through the Sensorite city. Desperate to save his companion's life, the Doctor searches for a cure.

As Ian's condition worsens, the Doctor still searces for a cure to the mysterious illness. However, the Doctor's efforts are undermined by the Sensorite City Administrator.

Having found a cure to the illness, the Doctor discovers that it is in fact deadly nightshade poisoning which has been introduced into the city water supply.
