The episode opens early morning with Detective Inspector Luke Bascombe and his partner DS Misha Frank on patrol. They share a light moment about Bascombe's son trying to skip school before receiving a report that leads them to storm the Miller family home with a squad. The police break down the door, causing chaos and property damage, and arrest 13-year-old Jamie Miller on suspicion of murder with a kitchen knife. Jamie is visibly distressed and having a breakdown, but the officers treat him gently, explaining his rights. The Miller family--parents Eddie and Mrs. Miller, and Jamie's sister--are shocked and confused, with the parents already planning to gather evidence to sue the police for the damage caused during the raid.

Jamie requests that his father Eddie act as his supervising adult during questioning, which worries DI Bascombe because Eddie is known to have a short temper and Bascombe recalls a previous case involving a father abusing his son. Meanwhile, a psychiatrist assesses Jamie, concluding he is bright and clever. Bascombe helps arrange a court-appointed lawyer, Paul Barlow, who is briefed on the case. The murder occurred the previous night at 10:13 pm, and Jamie has scratches on his arm; blood was found at the scene. However, Bascombe is uncooperative when Paul tries to investigate further.

The narrative shifts to CCTV footage from the night of the murder, showing Jamie following the victim, Katie, until about 9:47 pm. A confrontation occurs in a car park where Katie pushes Jamie, and he grabs her and throws her to the ground, making stabbing motions. Jamie's emotional state deteriorates as he insists he did not commit the murder, begging his father to talk to him. Eddie flinches at Jamie's touch but eventually hugs him, showing conflicted emotions.

At the police station, Jamie undergoes blood and mental health assessments, which he passes. The investigation intensifies as Bascombe and Frank visit Jamie's secondary school three days after the murder to interview classmates and seek a motive and the murder weapon. Katie's best friend Jade is distraught and hostile, even assaulting Jamie's friend Ryan, accusing him of involvement. Ryan initially cooperates but becomes evasive when the murder weapon is mentioned and eventually flees through a window. Bascombe chases and catches him outside the school.

Ryan reveals that the knife belonged to him and that he and another friend, Tommy, gave it to Jamie, believing Jamie would use it to intimidate Katie into retracting accusatory Instagram comments. Ryan is arrested for conspiracy to murder. Meanwhile, Eddie visits the site of Katie's murder to leave flowers, showing his personal turmoil.

Jamie's mood during police interviews fluctuates between friendly and aggressive. He admits to being tempted to grope Katie during their confrontation and that he borrowed the knife to threaten her but denies stabbing her. The psychiatrist informs Jamie that their sessions will end soon, which agitates him further. When Jamie demands to know if the psychiatrist likes him personally, she refuses to answer, leading to Jamie's outburst. A security guard forcibly removes Jamie from the interview room, leaving the psychiatrist visibly disturbed.

The episode ends with Jamie pleading his innocence, the police continuing their investigation, and the family grappling with the shock and uncertainty of the situation. The story is presented in a continuous one-shot style, heightening the tension and immersion throughout the unfolding events.
