The series' major differentiator lies in how the narrative is constructed. Each episode presents new clues but also raises doubts, causing viewers to constantly question who is telling the truth.
This format, known as "unreliable narrator," has been increasingly used in streaming productions — and here it is explored efficiently to keep audiences hooked until the very last minute.
Understanding the Story of Him & Her
The plot begins with a brutal crime: a woman is murdered in a forest in the small town of Dahlonega, United States. The case quickly gains attention and catches Anna's eye, who returns to journalism after being away due to personal trauma.
Meanwhile, Jack, her ex-husband, leads the police investigation.
The Past Connecting the Victims
As new crimes occur, a pattern begins to emerge:
- All victims have connections to Anna
- They studied together in the past
- They were part of the same group of friends
- They shared an old secret
This detail makes the case far more personal than it initially seemed.
The investigation becomes even more tense when Jack is also considered a suspect due to his involvement with one of the victims.
The Big Mystery: Who is the Killer?
Throughout most of the series, the script leads viewers to believe that Lexi Jones — an old school classmate who was bullied and underwent a radical transformation over the years — is responsible for the crimes.
Why Does Lexi Seem Guilty?
The narrative builds strong suspicion about her for several reasons:
- She has a traumatic past with the victims
- She was a victim of violence and humiliation
- She demonstrates deep resentment
- She is directly linked to the group
Everything suggests the murders would be revenge.
And that's precisely where the series tricks the audience.
The Plot Twist: Him & Her's Ending Explained
The major plot twist happens only at the end of the series — and completely changes the interpretation of the entire story.
After Lexi's death, apparently closing the case, a one-year time jump reveals the shocking truth.
The True Killer
The person responsible for the crimes is Alice, Anna's mother.
Yes, the character who seemed fragile, elderly, and showing signs of dementia is actually the mastermind behind everything.
She confesses to the murders in a letter left for her daughter.
Why Did Alice Kill the Victims?
The motivation behind the crimes is one of the series' most impactful points.
Alice discovered through old recordings that:
- Her daughter Anna was a victim of sexual violence in adolescence
- Other girls were involved in the episode
- Some of them witnessed or contributed to the trauma
Faced with this, Alice decides to act.
The Feeling of Revenge
She believes she is serving justice for her daughter. Each murder had a clear objective:
- Bring Anna back home
- Keep her close
- Rebuild the destroyed family
In her mind, everything was done out of love.
The False Dementia: A Crucial Detail
One of the script's most intelligent elements is how Alice manages to deflect any suspicion. She pretends to suffer from dementia, successfully hiding her true nature and capabilities throughout the series.
