The Doctor, Harry, and Sarah materialize on the Ark in Space, only to find it plagued by a mysterious infection and being manipulated by the sinister Professor Kellman, who is secretly working with the Cybermen.

The Doctor, Harry Sullivan, and Sarah Jane Smith use the Time Ring to travel back to the Ark in Space, where they left the TARDIS. Upon arrival, they discover that the station is deserted and plagued by a mysterious infection that has caused the deaths of many crew members. As they navigate through the station, they uncover that Professor Kellman, a civilian exographer, is secretly working with the Cybermen. The Doctor and his companions soon realize that the infection is not a natural plague but rather a result of the Cybermen's activities. The Cybermen, led by Vorus and Magrik, plan to use the gold on the planet Voga to convert humans into Cybermen. The Doctor and his friends must stop the Cybermen's plan while dealing with the infected crew members and the sinister Professor Kellman.

Act 1

The Doctor, Harry, and Sarah materialize on the Nerva Beacon, an orbital station they previously visited, only to find it deserted and littered with the bodies of its crew, victims of a mysterious "plague." They soon encounter the few remaining crew members: Commander Stevenson, Lester, and the enigmatic civilian exographer, Professor Kellman. While Stevenson and Lester struggle to maintain operations under quarantine, Kellman exhibits suspicious behavior, dismissing warnings of transmissions from a newly discovered asteroid named Voga and secretly tampering with logs. The Doctor, after a tense confrontation, undertakes a medical examination of an infected crewman, quickly deducing that the "plague" is not a natural disease but a calculated attack. His investigation leads him to connect Voga, a planet of gold, with the long-thought-extinct Cybermen, revealing them as the true architects of the crisis. Simultaneously, Kellman is exposed as a traitor, secretly communicating with the Cybermen and possessing gold. The Doctor's direct investigation of Kellman's cabin uncovers further evidence of his treachery, culminating in Kellman setting a dangerous trap for the Doctor, solidifying the immediate threat and the true nature of their predicament.
