The episode "The Zygon Inversion" begins with the Doctor, portrayed by Peter Capaldi, in a tense standoff with a Zygon named Bonnie, who has taken control of a group of Zygons in London. The Zygons, a shape-shifting alien race, have been living in peace with humans under a treaty, but tensions have escalated. Bonnie, who has assumed the form of a human, is holding the Doctor at gunpoint in a deserted church, while the real Clara, played by Jenna Coleman, is being held captive by Zygons in a nearby location.

As the Doctor tries to reason with Bonnie, he reveals that he understands her motivations and fears. He speaks to her about the importance of choice and the consequences of violence. Bonnie, however, is resolute in her belief that the Zygons must take control and eliminate the humans to ensure their survival. The Doctor attempts to appeal to her humanity, reminding her of the Zygon's original desire for peace and coexistence.

Meanwhile, Clara is in a separate location, where she is being interrogated by the Zygons. She is determined to escape and protect the peace between humans and Zygons. Clara manages to convince her captors that she is on their side, using her wit and intelligence to manipulate the situation. She learns that the Zygons are planning to launch an attack on London, which would lead to a catastrophic conflict.

Back in the church, the Doctor continues to engage Bonnie in a psychological battle. He uses a device to project images of the Zygons' home planet, showing her the devastation caused by war.
