The night passes without incident, but in the day, three guerrillas appear from the time vortex – Anat, a woman who is in command of the mission, and two men, Boaz and Shura. They come across a UNIT patrol and disintegrate the two soldiers while making their way to the house. In the study, the Doctor tries to reactivate the time machine, causing an alert to be sounded in the 22nd century. Shura enters, but the Doctor subdues him. Shura begs the Doctor to turn off the box, as in the future, a human Controller reports to the Daleks that the machine has been activated. The Daleks command that once the spacetime coordinates of the box are confirmed, whoever is using that device must be exterminated.
