The episode revolves around the Fifteenth Doctor (Ncuti Gatwa) and his companion, Ruby Sunday (Millie Gibson), who land on an alien planet in the midst of a large-scale war. When the Doctor steps on a landmine, he is forced to come up with a solution to disarm it without moving. In what is considered to be a bottle episode, Varada Sethu, who was not expected to debut in Doctor Who until the following series, makes a guest appearance as Mundy Flynn.
