The Doctor is taken for execution, despite Nyssa's attempts to save him, and placed in a dispersal chamber. Unbeknownst to the High Council, The Doctor's mind has been taken into the Matrix, the repository of all Time Lord knowledge, while his body is hidden. The Renegade, who demands an opportunity to return to the Universe it once inhabited, contacts him. The truth of the aborted execution is discovered by the

In Amsterdam, the Doctor's former companion Tegan is looking for her cousin Colin Frazer. She is greeted by his friend Robin Stuart, who explains that Colin disappeared while they were crashing in the crypt of the Frankendael mansion. The Renegade, which has established its base at the Frankendael, finds them and uses Tegan as bait to force the Doctor to obey him. The Doctor is returned to normal space on Gallifrey where he makes for the High Council Chamber. Time Lord Councillor Hedin is revealed as the traitor who transmitted the bio-data. Hedin is in awe of his master

, first of the Time Lords and pioneer of time travel. Hedin wishes to release Omega from his exile in a universe of antimatter, not realising the great Time Lord has been driven insane by his years of solitary confinement. The Castellan kills Councillor Hedin, but this does not prevent Omega using the Arc of Infinity to seize total control of the Matrix and come to Earth. When he peels his decayed mask away, he reveals the features of the Doctor, whom he now perfectly resembles. Omega leaves for Amsterdam with the Doctor and Nyssa in pursuit. Within a short time, the Doctor's prediction of an unstable transfer begins to come true: Omega's flesh decays and it is clear his new body is not permanent. When the Doctor and Nyssa catch up with him, it is a painful task for the Doctor to use the Ergon's antimatter converter on Omega, expelling him back to his own universe of antimatter. The Time Lord High Council on Gallifrey detects the end of the threat. Once Tegan has checked on her cousin's progress in hospital, she decides to rejoin the TARDIS crew.

Story writer Johnny Bryne had some trouble at first because the producers wanted a plot that made the Amsterdam setting a key factor in the course of events, rather than him just happening to be there. Part One was broadcast on a Monday in contrast to the rest of this season's episodes, which were all transmitted on consecutive Tuesday and Wednesday evenings.
