Materialising on an island of glass in a sea of acid, the Doctor, Susan, Ian and Barbara find themselves chosen to embark on a perilous quest set by Arbitan, Keeper of the Conscience of the planet Marinus.

The Conscience machine has the power to control the minds of everyone on Marinus, and it is in danger of falling into the hands of the sinister Yartek, leader of the alien Voord. To prevent disaster, the TARDIS crew must recover the machine's operating keys, hidden in various locations around the planet. Others have attempted this task before - but none have returned.

From Morphoton to Millennius, battling ice soldiers and deadly plants, overcoming hypnotic conditioning and hostile witnesses, this trek across Marinus promises to be the four travellers' most challenging adventure yet.
