Episode one

As the Earth cargo ship C982 moves through hyperspace, it narrowly avoids a collision with the TARDIS, which dematerialises out of the way and rematerialises in the ship's hold. The Third Doctor determines that they are in the 26th century. Jo sees a ship come alongside and hears a strange, high-pitched buzz. The ship shimmers, turning into a Draconian Galaxy-class battlecruiser. The two pilots, Stewart and Hardy, send out a distress signal and prepare for battle. When Hardy goes to get weapons, he meets the Doctor, but, thanks to the sound emitted by the enemy ship, he sees the Doctor and Jo as Draconians whilst Jo sees Hardy as a Drashig. Hardy escorts them at gunpoint as the Draconian captain orders C982 to surrender its cargo or be destroyed.

On Earth, the President and the Draconian ambassador (who is also the Emperor's son) accuse each other of attacking their ships and violating the frontier between the two empires established by treaty. General Williams reports to the President that a mission to rescue C982 is being prepared. Williams's hostility to the Draconians is well known — it was his actions that started the last war between the two — and the Prince believes Williams wants war again, a war, the Prince warns the President, that will see Earth destroyed. News of the attack spreads and anti-Draconian riots break out on Earth. The opposition calls for the government to take action.

The Ogrons board.

Locked up in C982's hold, the Doctor deduces that the strange sound was some kind of sonic hypnosis device that caused Hardy and Jo to see what they most feared. As the boarding party burns through the airlocks, Hardy gets the Doctor and Jo to use as hostages, but when the airlock door bursts open, the boarders are not Draconians, but Ogrons. The Ogrons stun the two pilots and the Doctor. They tie up Jo and take the ship's cargo and the TARDIS as they leave. When the Doctor revives and releases Jo, she tells him what the Ogrons did and wonders if they are working for the Daleks, as they were when she first met them. The Doctor points out that the Ogrons are mercenaries, and work for whoever employs them. When the rescue party arrives, Hardy and Stewart have stopped hallucinating, but with their memories garbled, they accuse the Doctor and Jo of being Draconian traitors...
