Like Adolescence With More Twists: Nicola Walker’s “Amazing” Crime Drama A Mother’s Son Is Coming to Netflix
Nicola Walker is back in the spotlight, and crime drama fans have another compelling mystery to add to their watchlists. A Mother’s Son, the gripping ITV thriller starring the acclaimed British actress, is heading to Netflix, bringing a disturbing murder investigation, a family torn apart by suspicion, and a mother forced to confront an unthinkable possibility.
First broadcast in 2012, the two-part drama shares some similarities with Adolescence, particularly its focus on a schoolboy suspected of killing a female classmate and the devastating impact the case has on those around him. Set in a rural Suffolk community, the story gradually unravels as suspicion spreads and family loyalties are put to the test.
With an impressive British cast, an unsettling family dilemma, and plenty of twists to keep viewers guessing, A Mother’s Son is well worth revisiting. Here’s everything you need to know about the drama, including its storyline, cast, Netflix release date, and what viewers have thought of it.
What Is A Mother’s Son About?
Originally aired on ITV in 2012, A Mother’s Son follows Rosie Cutler, played by Hermione Norris, whose seemingly happy family life begins to fall apart when she starts to suspect that her son is hiding something terrible.
Rosie lives with her husband, Ben Banks (Martin Clunes), and their four children. Their family appears settled until a shocking discovery changes everything: Rosie finds bloodstained trainers in the bedroom of her son, Jamie Cutler (Alexander Arnold).
The discovery comes just days after a local schoolgirl is murdered, leaving Rosie to wonder whether Jamie could be responsible. As the police investigate the girl’s death, her suspicions place her in an agonising position. Should she tell the authorities what she has found, potentially destroying her relationship with her son, or keep quiet in the hope of protecting him?
The investigation is led by D.C. Sue Upton, played by Nicola Walker, and D.C.I. Thomas McCleish, played by Charles Daish. As the case develops, the line between a mother’s instinct to protect her child and her responsibility to face the truth becomes increasingly difficult to navigate.
Much like Adolescence, the drama explores the emotional consequences of a murder investigation, examining how suspicion can transform family relationships and unsettle an entire community. Its central mystery is made all the more compelling by Rosie’s struggle to reconcile her love for her son with the possibility that he may have done something horrific.
Who Is in the Cast of A Mother’s Son?
Nicola Walker leads an accomplished ensemble featuring several familiar faces from British television. Hermione Norris and Martin Clunes play the parents at the heart of the story, while a younger cast portrays the children whose lives are caught up in the unfolding mystery.
Here’s the full cast list:
- Hermione Norris as Rosie Cutler
- Martin Clunes as Ben Banks
- Paul McGann as David Cutler
- Alexander Arnold as Jamie Cutler
- Ellie Bamber as Olivia ‘Livvy’ Cutler
- Jake Davies as Rob Banks
- Antonia Clarke as Jess Banks
- Juliet Yorke as Lorraine Mullary
- Annabelle Apsion as Kay Mullary
- Nicola Walker as D.C. Sue Upton
- Charles Daish as D.C.I. Thomas McCleish
Walker is particularly well known for bringing depth and complexity to her television roles. Her performance as D.C. Sue Upton adds another notable crime drama credit to a career that has included a range of memorable characters.
How to Watch A Mother’s Son on Netflix
Fans won’t have to wait long to revisit this crime thriller. Although A Mother’s Son originally aired on ITV, it is scheduled to arrive on Netflix on Sunday 2 November 2025.
The series consists of two episodes, each running for approximately 45 minutes. That makes it an ideal choice for viewers looking for a tightly paced crime drama they can finish in one sitting.
With its small-town setting, unsettling murder mystery, and emotionally charged central storyline, the series offers a compelling alternative for anyone who enjoys dark, character-driven thrillers.
Is A Mother’s Son Worth Watching?
The drama has received positive responses from critics and viewers, with praise for its tense atmosphere and absorbing mystery. It has been described as “tense, absorbing and thrilling”, while its portrayal of the anxieties and uncertainties of parenthood has also been singled out for its unsettling quality.
On IMDb, A Mother’s Son holds a rating of 6.8 out of 10.
One of the story’s most compelling elements is its exploration of a parent’s worst fear: discovering that the child they love may be capable of something terrible. Rosie must grapple with the possibility that her instincts about her son could be wrong, while also confronting the consequences of ignoring the evidence in front of her.
The resulting tension gives the series an emotional dimension beyond the murder investigation itself. Rather than focusing solely on finding the culprit, the drama examines the personal cost of suspicion and the difficult choices that arise when family loyalty clashes with the search for the truth.
For viewers who enjoy mysteries that combine police investigations with complicated family relationships, A Mother’s Son is a strong addition to the watchlist.
What Other Crime Dramas Can You Watch?
If A Mother’s Son leaves you wanting more mysteries, there are several other dramas worth exploring, including another standout series featuring Nicola Walker.
River
Available on ITVX, River offers an unusual take on the detective genre by blending crime-solving with supernatural elements.

All episodes of River are available to stream on ITVX.
Ludwig
For something with a different approach to detective work, Ludwig is available on BBC iPlayer.
Starring David Mitchell and Anna Maxwell Martin, the series follows a man who impersonates his missing twin brother, a police officer, in an attempt to discover what happened to him. As he investigates his brother’s disappearance, he also discovers an unexpected talent for solving crimes.
The combination of a missing-person mystery and an unlikely amateur detective makes Ludwig another engaging option for fans of British crime television. You can watch it on BBC iPlayer.
Whether you’re drawn to the family tensions of A Mother’s Son, the supernatural mystery of River, or the unusual detective story at the heart of Ludwig, there’s plenty to explore if British crime dramas are your kind of television.
