Publisher's summary
The Doctor wants a peaceful afternoon playing guitar in his study. Keira wants the Doctor to take her from Earth to the planet Calandra. Reluctantly, the Doctor agrees. But when they arrive, Calandra isn't how Keira remembers. Something's gone very wrong...

Plot
Keira breaks into the Doctor's study and, at gunpoint, forces him to take her to Calandra in the TARDIS. Despite her wanting to tie him up and leave him in the ship, he goes with her onto the planet and finds the population being put to sleep by street-sweeping robots with temporal technology which takes away about ten hours of the victim's time stream. Science Leader Vetch and Security Leader Milla arrive and arrest the two of them, recognising Keira from her previous visit.

Keira reveals that she is a Time Agent and came to observe the Calandrans' civilisation. She disassembled her vortex manipulator to bypass the limits placed on it and resorted to assisting the Science Bureau to find a way to repair it, making advances in matter transmission for the transit system and replication to reproduce parts of her manipulator. This has resulted in the creation of duplicates of those who use the transit system, known as the Confused. Using his psychic paper, the Doctor begins his investigations to stop the process, which is draining those being duplicated, including Vetch.

Milla attempts to incinerate Keira, but she escapes using her gun and they have a shootout which leads Milla to order the sweepers to kill her. Keira reaches the Doctor, who has decided to create a dispersal field to convert the Confused back into transmat streams and merge with their original selves, and flees with him and Vetch. The Doctor holds back Milla and the sweepers, being less vulnerable to them due to his long life, and reveals that he knows that Milla is a Confused and that she killed her original. As a result, the dispersal field will kill her. She shoots Vetch and Keira subdues her whilst the Doctor completes the field.

The Calandrans are restored, healing Vetch from his wound, and the sweepers return to their usual job. Keira gives her vortex manipulator to the Doctor and returns to the TARDIS with him, telling him about a rogue Time Agent who is causing damage to history. The Doctor takes her back to Bristol and find that St Luke's University and the rest of the city has disappeared, a change to time for which he believes that Keira is responsible.
