Plot
While her companions try to get her to talk about her search for the Master, the Doctor learns that a Judoon platoon stationed near the moon has descended upon Gloucester and put a forcefield around the city in search of a fugitive. The Doctor manages to bypass the forcefield and arrives in Gloucester. Upon landing and unbeknownst to the Doctor, Graham is teleported to a stolen spaceship piloted by Captain Jack Harkness who mistakes Graham for the Doctor. The Doctor intervenes when the Judoon try to attack the apartment of Lee and Ruth Clayton, and stalls them long enough to question the couple and find a hidden box. Lee refuses to answer the Doctor's questions, but he covers the group's escape, turning himself in to the Judoon before being killed by their contractor, Gat, who recognises him as the fugitive's associate.Whilst the Doctor flees with Ruth to Gloucester Cathedral, Ryan and Yaz are teleported to Harkness' ship, which is now being attacked by its rightful owners. When Harkness learns the Judoons' forcefield prevents him from teleporting the Doctor, he is forced to ask the Doctor's companions to tell the Doctor to beware of the "lone Cyberman" and to not give it what it wants. He is forced to teleport due to the ship's anti-theft attack system while Graham, Ryan, and Yaz are transported back to Gloucester. The Doctor and Ruth are soon surrounded by the Judoon in the cathedral. Ruth reflexively attacks them, forcing them to retreat after ripping off their commander's horn. With Ruth unable to explain herself, she reveals Lee sent her a text before his death that leads them to a lighthouse where she grew up.
There, the Doctor finds a TARDIS buried outside under a blank gravestone. Ruth, meanwhile, enters the lighthouse and, breaking an alarm box, is engulfed in energy which restores her memory. Ruth then reveals her true identity as a version of The Doctor. With neither remembering the other, the Doctor assumes Ruth to be an unknown past incarnation while Ruth believes the Doctor to be a future version of her, and reveals that she used a chameleon arch to hide herself from her former associate Gat. Ruth's TARDIS is then taken aboard the Judoon ship, and the Doctor and Ruth confront Gat, who is revealed to be a Time Lord with orders to retrieve Ruth. Against Ruth's orders, the Doctor introduces herself, and shows Gat a vision of the destroyed Gallifrey that she saw, confirming that Ruth and Gat are in her past, though she cannot remember them. Gat is killed when she fires a sabotaged weapon confiscated from Ruth.
After the Doctor is dropped back to Gloucester by Ruth, she is reunited with her companions, who relay Harkness's message. Confused by recent events, the Doctor senses that something is coming for her.
