When Adolescence premiered in March 2025, it quickly earned a reputation as one of the most chilling, unsettling U.K. television series in recent memory. After the four-part miniseries hit Netflix in the U.S., viewers were left shaken—and full of questions. Was Jamie Miller, the chilling lead played by breakout star Owen Cooper, inspired by a real person?
Below, Hollywood Life breaks down the gripping one-shot drama and how creators Jack Thorne and Stephen Graham brought the Emmy Award-winning haunting story to life.
What Is Adolescence About?
Adolescence follows 13-year-old Jamie’s arrest and how his family’s world is turned upside down in the aftermath. Accused of murdering a classmate named Katie, Jamie faces the consequences of his actions while his parents confront their worst nightmare and as detectives investigate his motive.
Did Jamie Kill Katie in Adolescence?
Yes, Jamie’s crime is revealed in the first episode when he is interviewed by investigators. Though he insists he hasn’t “done anything wrong” to his father (played by co-creator and writer Stephen), police show them surveillance footage of Jamie stabbing Katie to death. In episode 4, Jamie tells his dad that he’s changing his plea from not guilty to guilty.
Is Adolescence Based on a True Story?
Adolescence is not based on a particular real-life crime. Stephen informed Netflix’s Tudum that he was inspired to work on the script when he heard about an incident in the U.K. when a “young boy [allegedly] stabbed a girl.”
“It shocked me,” Stephen elaborated, adding, “I was thinking, ‘What’s going on? What’s happening in society where a boy stabs a girl to death? What’s the inciting incident here?’ And then it happened again, and it happened again, and it happened again. I really just wanted to shine a light on it, and ask, ‘Why is this happening today? What’s going on? How have we come to this?’”
Co-creator Jack added that he, Stephen and director Philip Barantini were fascinated by the concept of male rage, and they began “questioning with some intensity” who they were as men. “That is a journey I’ve never gone on as a writer before, and it scared me and excited me because it felt like we had something to say,” Jack pointed out.
Adolescence‘s Ending Explained
The final episode of Adolescence ends with Jamie calling his dad to reveal he’s changing his plea to guilty. Stephen’s character, Eddie Miller, then reflects on how his parenting played a role in his son’s life. He and Jamie’s mother, Manda Miller (played by Christine Tremarco) discuss the warning signs they witnessed with Jamie, including the teen staying up late at night on his computer.
The final moments of episode 4 show Eddie sobbing in Jamie’s room and tucking in his stuffed animal under the covers before apologizing to Jamie, fully accepting his fate.
“I’m sorry, son,” Eddie says through tears, before admitting, “I should have done better.”
Will There Be More Episodes of Adolescence?
No, Adolescence ends with episode 4, and so far, there is no word on the potential for a season 2.
