"Into the Dalek" is the second episode of the eighth series of the British science fiction television programme Doctor Who, written by Phil Ford and Steven Moffat, directed by Ben Wheatley, and first broadcast on 30 August 2014. Ford has previously written for the show, co-writing 2009's "The Waters of Mars", and was a lead writer for spin-off series The Sarah Jane Adventures. Starring Peter Capaldi and Jenna Coleman the episode also introduces Samuel Anderson as Danny Pink. It was watched by 5.2 million viewers in the UK on its initial transmission, according to unofficial overnight figures, taking a 24.7 per cent share of the entire TV audience and making it the second-highest rated programme of the evening, with the final numbers giving a total of 7.29 million viewers.

The Doctor saves rebel fighter Journey Blue from her space shuttle, which is under attack by Daleks. He returns her to the rebel command ship Aristotle, a former hospital ship converted for military use. To prevent his being executed as a potential Dalek spy, Journey offers the Doctor's services to assist with their "patient": a damaged Dalek the rebels found floating through space. This Dalek, surprisingly, declares that the Dalek race is evil and must be destroyed. Somehow, the damage inflicted upon it has given it a sense of morality—a "good" Dalek.

Meanwhile, Danny Pink, an Afghanistan war veteran emotionally scarred from his experiences, begins teaching Maths at Coal Hill School. In the staff room, Danny is introduced to Clara Oswald, who invites him to a retirement party for one of their colleagues. Danny declines, feeling awkward due to an obvious connection between them. However, when Clara finds him in his classroom despairing over his actions, she invites him out for a drink instead. He agrees. Back at her office, Clara comes face to face with the Doctor, whom she hasn't seen in three weeks since he left her to get coffee in Glasgow (as seen in "Deep Breath"). He tells her that he needs her help. He begins by asking her for her honest opinion: is he a good man? Clara hesitantly replies that she doesn't know. The Doctor then briefs her on what happened aboard the Aristotle. Clara agrees to assist his efforts to help the "good" Dalek, despite the Doctor's contention that Daleks cannot be turned good.
