Netflix’s The Trap ends with Robert Lenzen admitting that he stabbed Anna six times, although her body had eight stab wounds. The revelation suggests that Lisa Konrad may have attacked her own sister after Robert escaped, leaving the German psychological thriller with a disturbing, deliberately ambiguous ending.
Spoiler Warning: This article contains major spoilers for all six episodes of The Trap, including the final episode, “The Truth.”
Released on October 13, 2026, The Trap follows bestselling author Lisa Konrad (Friederike Becht), who has spent nearly a decade isolated in her home after witnessing her younger sister’s murder. When she recognizes journalist Robert Lenzen (Hans Löw) on television, she becomes convinced that he is the killer and prepares an elaborate plan to expose him.

However, the final episode reveals that Lisa’s memories of Anna’s death are incomplete, raising questions about what actually happened that night and why she has spent so many years avoiding the outside world.
The Trap Ending Explained: Who Killed Anna?
Robert Lenzen is responsible for attacking Anna, but the finale strongly suggests that Lisa may have delivered the final two stab wounds.
During their confrontation, Robert admits that he had been having an affair with Anna while married to his wife, Alexandra. Their relationship became increasingly complicated when Robert decided to end it and return to his family.
Anna refused to accept his decision and threatened to expose their affair. Robert eventually lost control during their argument and stabbed her six times before fleeing the scene.
Lisa arrived shortly afterward and discovered her sister covered in blood. Although she briefly saw Robert, the trauma surrounding Anna’s death left her with fragmented memories that continued to trouble her for years.
The most important detail emerges when Robert insists that he stabbed Anna only six times. According to the information Lisa had included in her manuscript, Anna suffered eight stab wounds, meaning two injuries remained unexplained.
As Ready Steady Cut’s Episode 6 recap also observes, this discrepancy changes the meaning of the entire investigation, particularly because Robert had already tried to convince Lisa that she was responsible for her sister’s death.
Did Lisa Actually Kill Her Sister Anna?
The finale strongly implies that Lisa inflicted the remaining two stab wounds, although the series never explicitly shows her doing so.
Throughout The Trap, Lisa remembers Anna as someone whose death destroyed her life. However, the flashbacks gradually reveal that their relationship was considerably more troubled than Lisa initially acknowledges.
Anna resented her sister’s success, and their relationship had become strained by jealousy, arguments, and unresolved resentment. These details suggest that Lisa’s memories of Anna may have been shaped by guilt and trauma.
Robert uses this history to manipulate Lisa, repeatedly suggesting that she murdered Anna and suppressed the memory afterward.
Initially, these accusations appear to be another attempt to escape responsibility. Robert has already demonstrated his willingness to manipulate Lisa, making his claims difficult to trust.
However, the discrepancy between the six wounds he admits inflicting and the eight recorded in Lisa’s account gives his accusation greater significance.
One possible explanation is that Lisa encountered Anna while she was still alive and attacked her during an emotionally unstable moment. If that happened, she may have subsequently blocked out her involvement and reconstructed the memory around Robert’s presence.
The series deliberately leaves this interpretation unconfirmed. Robert admits to the initial attack, but viewers never receive definitive evidence establishing who inflicted the final two wounds or whether those injuries caused Anna’s death.
Why Did Robert Manipulate Lisa?
Robert spends much of the series trying to undermine Lisa’s confidence in her own memories because he realizes she could expose his involvement in Anna’s murder.
After discovering that Lisa intends to confront him, he begins manipulating her surroundings and psychological state.
He admits to several actions during their final confrontation:
- He uses music associated with Lisa’s trauma to provoke a psychological reaction.
- He puts GHB in her water and a hallucinogenic substance in her coffee.
- He bribes a photographer to help support his deception.
- He attempts to convince Lisa that she murdered Anna and constructed false memories to protect herself.
Robert’s fabricated evidence, including footage intended to establish that he was in Afghanistan when Anna died, adds to Lisa’s confusion.
His behavior also explains why the audience initially distrusts the suggestion that Lisa murdered her sister. Robert repeatedly lies and manipulates evidence, making it reasonable to believe that his accusations are another attempt to escape punishment.
The ending becomes more complicated when his confession confirms that he attacked Anna while leaving the question of the remaining injuries unanswered.
Why Does Robert Kill Himself in The Trap?
Robert dies by suicide after Lisa confronts him and his attempt to regain control of the situation fails.
During their confrontation, Lisa strikes him with an ashtray and attempts to escape. Robert follows her outside, where publisher Norbert Rudow and literary agent Pia arrive while the police are being contacted.
With his involvement in Anna’s murder exposed and the possibility of arrest approaching, Robert takes his own life.
His death prevents investigators from questioning him further about Anna’s murder, leaving Lisa with a confession that contains both an admission of guilt and an accusation against her.
Robert’s decision also reflects his behavior throughout the series. He repeatedly tries to control what others believe about Anna’s death, and his final action prevents him from facing the consequences of his admission.
Still, his suicide does not establish whether Lisa was involved in the murder. That uncertainty continues into the closing moments.
Why Does Lisa Delete Robert’s Confession?
Lisa deletes the recorded confession after Robert’s death, even though obtaining that evidence was the central purpose of her elaborate plan.
The decision becomes particularly suspicious because the recording contains Robert’s admission that he stabbed Anna six times, along with his insistence that he did not inflict the remaining injuries.
If Lisa believes she might have attacked Anna, keeping the recording would expose the unanswered questions surrounding her own involvement.
Deleting it allows her to eliminate evidence that challenges the version of events she has believed for almost ten years.
However, the scene also supports another interpretation. Lisa may simply want to escape the traumatic confrontation and remove the final reminder of Robert’s manipulation.
The timing of her decision gives the first explanation greater weight. After spending years searching for evidence against Robert, Lisa chooses to destroy the recording once it begins pointing toward her possible responsibility.
The deletion suggests that Lisa recognizes the implications of Robert’s confession, even if she remains unwilling to confront them openly.
What Does Lisa’s Smile Mean in the Final Scene?
Lisa’s smile in the closing moments suggests that she has found a way to move forward while keeping the complete truth about Anna’s death hidden.
For much of the series, Lisa struggles with fear, grief, and the belief that her sister’s murderer remains free. Robert’s death removes the person she has blamed for destroying her life.
However, the unexplained wounds leave open the possibility that Lisa has also escaped responsibility for her own actions.
Her smile can therefore be interpreted as a sign of relief, acceptance, or a darker recognition that nobody will uncover what happened after Robert fled Anna’s home.
The ending becomes particularly significant when viewed alongside Lisa’s career as a novelist.
Throughout the series, she creates stories and reconstructs events through fiction. Her memories of Anna follow a similar pattern, with certain details emphasized while others remain buried.
This connection suggests that Lisa may have spent years constructing a version of her sister’s death that allows her to continue living without confronting everything she remembers.
As The Cinemaholic’s analysis also explores, Lisa’s ability to suppress uncomfortable memories gives the final scene another layer of meaning.
The smile does not definitively establish her guilt, but it reinforces the possibility that she understands more about Anna’s death than she is prepared to admit.
What Does the Ending of The Trap Really Mean?
The ending explores how guilt, grief, and unreliable memories can influence someone’s understanding of the past.
Lisa begins the story believing that identifying Anna’s murderer will finally allow her to recover from years of psychological suffering.
Her investigation succeeds in establishing Robert’s involvement, but the confession also exposes inconsistencies in her memories.
The eight stab wounds become the central clue because they connect Robert’s confirmed actions to a period that Lisa cannot fully explain.
Meanwhile, the novel she writes to expose Robert becomes an important reflection of her own psychological state. By turning Anna’s murder into a fictional narrative, Lisa gains control over how the story is presented and interpreted.
The final revelation suggests that this same process may have shaped her memories for years.
There is also a reason the series repeatedly questions which character is controlling the investigation. Lisa designs the original trap for Robert, while Robert develops his own plan to destroy her credibility.
By the finale, Lisa’s pursuit of the truth has forced her to confront the possibility that her account of Anna’s death is incomplete.
The story ultimately leaves viewers with two established facts: Robert attacked Anna, and Lisa destroyed his confession. Whether she was responsible for the remaining wounds remains the central unanswered question.
Is The Trap Based on a Book?
Yes. The Trap, originally titled Die Falle, is based on the bestselling novel by German author Melanie Raabe.
The six-part Netflix adaptation was written and directed by Isabel Kleefeld, who previously worked on the acclaimed German thriller Dear Child.
According to Netflix’s official production announcement, the adaptation stars Friederike Becht as Lisa Konrad, Hans Löw as Robert Lenzen, Matthias Brandt as Norbert Rudow, and Josephine Thiesen as Anna.
The series uses Lisa’s writing, shifting memories, and tense confrontations to explore the uncertainty surrounding her sister’s death.
Will There Be The Trap Season 2?
Netflix has not announced a second season of The Trap as of October 14, 2026.
The streaming service describes the production as a six-part limited series, with all episodes released on October 13.
Although the finale leaves questions about Lisa’s involvement in Anna’s death, the central investigation reaches its conclusion with Robert’s confession and subsequent death.
The unresolved final twist therefore works as an intentional part of the story’s psychological mystery rather than confirmation that another season is planned.
All six episodes are currently available to watch on Netflix.
