Having escaped their cell by using the device on one of the Daleks, the Doctor and Codal encounter Rebec and Taron, who had been mounting a rescue operation, and the group flees down the corridors with the Daleks pursuing them. They make their way to a refrigeration chamber and discover the hibernating Dalek army. With the Daleks cutting their way through the door into the chamber, the Doctor improvises a hot-air balloon and the group escape up a shaft to the surface. Codal and Rebec heave a boulder down the shaft, destroying a pursuing Dalek, and they narrowly avoid a second patrol sent from the surface. They soon reunite with Latep and Vaber, who is keen to attack the Daleks as soon as possible, while Taron urges caution.
