The Doctor is given the task of reassembling the six parts of the Key to Time at the behest of the White Guardian. He and his new companion Romana, go to the icy world of Ribos in search of the first segment where they encounter a pair of con-men and a megalomaniac ex-tyrant.

Prisoners of the maniacal Graff Vynda K, the Doctor and Romana must break out and pursue the first segment – even as Unstoffe takes it into the most dangerous place on Ribos.

Trying to obtain the first segment of the Key to Time, the Doctor and Romana are swept up in an elaborate con. The target – the homicidal Graff Vynda K.

Trapped in the catacombs between a mad warlord and ravenous monsters, the Doctor and Romana work desperately to obtain the segment of the Key to Time - and escape alive.
