If you’re looking for a must-binge crime thriller series this week, Netflix’s The Trap (Original title: Die Falle, TV Series 2026) is worth checking out. Based on Melanie Raabe’s 2015 bestselling German novel of the same name, the six-episode series follows a reclusive writer who becomes obsessed with finding her sister’s killer after spending ten years hiding from the world. The series has the same dark psychological thriller vibes as Alfonso Cuarón’s Disclaimer and Claire Danes starrer The Beast in Me, keeping you guessing about what really happened and whether the protagonist is a reliable narrator of her own past.
As Lisa digs deeper into her sister’s murder, the line between what she remembers and what she believes begins to blur, leaving us questioning whether her suspicions are justified or whether years of trauma have distorted her perception of reality. As the story unfolds, the more Lisa learns about Anna’s murder, the less certain she becomes about what really happened. The series is not just about finding the killer. It also shows how grief, guilt, and years of trauma can mess with your memory and make you question your own version of the truth.
In this article, I break down the entire plot of Netflix’s crime thriller. Please note that the article contains major spoilers throughout.
The Trap (TV Series 2026) Episode 1 ‘The Monster’ Recap:
Lisa Konrad suspects Robert Lenzen of murdering her sister
Episode 1 introduces Lisa Konrad, a reclusive writer who has spent the last ten years trying to escape the trauma of her sister Anna’s brutal murder. After the tragedy, Lisa was admitted to a psychiatric hospital. Upon her release, she changed her identity and moved into her publisher Norbert’s guest villa. In exchange, she agreed to give him more than 50% of the royalties from her next five books. A decade later, she is still living there, afraid that Anna’s killer is walking free.
Lisa has barely told anyone about what happened to her sister. One night, however, she spots a man on a news broadcast whom she believes is Anna’s killer. The sight sends her into a panic, but she manages to remember the channel and the reporter’s name. After some digging, Lisa identifies the man as Robert Lenzen, a senior editor at Reflekt Berlin who has a 12-year-old daughter and appears to lead a perfectly respectable life. The problem is that Chief Detective Leon Weber, who investigated Anna’s murder, has already closed the case. Lisa decides to take matters into her own hands and find a way to get Robert’s DNA. Her therapist, Dr Anger, dismisses her suspicions as anxiety and an overactive imagination, but Lisa refuses to let it go.
Instead, she begins writing a crime novel titled My Sister, using the protagonist Sophie to retell her own experiences. She plans to send the manuscript to Robert in the hope of unsettling him into confessing. She also arranges an interview with him. As the episode closes, details about Anna’s murder reveal that two DNA samples were found on her body, offering a possible lead in a case that may not be as hopeless as Lisa fears.
The Trap (TV Series 2026) Episode 2 ‘The Novel’ Recap:
Robert Lenzen discovers Lisa’s real identity
Episode 2 begins with Lisa’s publisher, Norbert Rudow, confronting her about her new thriller. He worries that the book could confuse readers, especially since she hasn’t published anything in two years. Lisa manages to convince him to release it without edits, but she has one condition: Robert Lenzen must interview her.
As Lisa revisits the events surrounding her sister Anna’s murder, we learn more about her breakdown. Hearing “Somebody That I Used to Know” once triggered vivid visions of Anna’s death. Her boyfriend, Marc, helped her get admitted to a psychiatric hospital but never visited her afterward. Norbert, meanwhile, offered her his guest villa when his publishing house was struggling financially. He also knew Anna, who had once pitched an advertising idea to his company and recommended Lisa as a writer. Norbert later reveals that he visited Anna’s apartment after her murder, where crime scene examiner Narges asked for his DNA. Overwhelmed by the situation, he left, although he claims his DNA was eventually collected.
Lisa continues working on My Sister, describing how she found Anna covered in blood and picked up the murder weapon. She remains convinced that Robert is responsible. Meanwhile, Narges begins questioning Detective Leon Weber’s handling of the case and wonders whether Lisa herself could be involved. The mysterious letters “LI,” found written in blood beneath Anna’s hand, add another layer to the investigation. Elsewhere, Robert discovers that Lisa Konrad is a pseudonym and asks his IT colleague, Bassem, to uncover her real identity. When Lisa finds out that a photograph of her villa has surfaced, she fears her location has been exposed. She starts self-defence training and installs surveillance equipment, but Robert has already found her home and is watching her from the bushes.
The Trap (TV Series 2026) Episode 3 ‘The Training’ Recap:
Lisa’s new novel puts her at risk
Episode 3 sees Lisa becoming increasingly paranoid as she prepares for the possibility that Anna’s killer might come after her. While training in self-defence, she struggles to react quickly enough, and her trainer hints that she may have a history of addiction. Lisa responds by throwing away all her medication and deciding to stop taking it altogether. Soon, even a noise outside is enough to make her panic, though she eventually discovers that it was only a deer.
Meanwhile, Robert learns that he will receive Lisa’s manuscript a week before their interview. He later plants a tracker in Yuma’s bag while working at the cinema counter, hoping it will lead him to Lisa. His plan works, and he soon finds her villa and begins keeping an eye on the property. Lisa’s behaviour also worries Dr Anger, who notices her growing anger, isolation, and paranoia. She refuses to take her medication and suspends their therapy sessions so she can focus on finishing her novel. During dinner with Norbert, Dr Anger suggests that Lisa is trying to process her trauma, but Norbert fears she might uncover something from her past.
Determined to get answers, Lisa brings Major Nils Christensen to the villa to teach her interrogation techniques. After questioning him for 14 hours, she finally explains what she wants to achieve, and he agrees to help. Despite barely sleeping, Lisa finishes her manuscript and sends it to Norbert and Robert, ending it with a direct challenge to the killer. The next morning, Lisa finds her dog, Bukowski, caught in a bear trap outside. Unable to face going out, she gets help from Norbert and Yuma. Although Norbert praises her book, he warns her against revealing the killer’s identity. Lisa eventually collapses, forcing Dr Anger to step in and give her medication.
The Trap (TV Series 2026) Episode 4 ‘The Interview’ Recap:
Lisa holds Robert at gunpoint
Episode 4 begins with Lisa preparing for her interview with Robert Lenzen, with a gun hidden under her desk in case things go wrong. When Yuma calls to tell her that someone has slashed her car tyres, Lisa insists that she stay away from the villa. Norbert also tries to call off the interview, but Lisa refuses to listen and threatens him when he tries to stop her. Robert arrives with his colleague Jannick Lucic, who is there to photograph the interview. Lisa takes her medication beforehand, following Nils’s advice, but the camera flashes bring back painful memories of her time with the police. Things get even worse when Jannick secretly slips something into her coffee, leaving her disoriented and hearing the song linked to her traumatic past.
Lisa tries to get Robert’s DNA during their conversation, but he refuses both her cigarette and coffee. Nils then calls with some devastating news about Anna’s case. The DNA samples have become unusable, and the evidence has been destroyed. Robert overhears the conversation and realises that Lisa has nothing concrete to connect him to the murder. The interview grows increasingly uncomfortable as Lisa questions Robert about his failed marriage and whether he has ever raped a woman. He retaliates by criticising her novel, arguing that she has turned Anna into an idealised character. He also suggests that Sophie, the protagonist, might have killed her own sister.
That accusation pushes Lisa over the edge. She pulls out her gun and demands that Robert confess to Anna’s murder. When he attacks her, Lisa uses her self-defence training to overpower him. She then fires a shot into the wall to scare him and gives him a choice: confess to killing Anna or risk being shot herself.
The Trap (TV Series 2026) Episode 5 ‘The Confession’ Recap:
Lisa begins to suspect she killed her own sister
Episode 5 picks up with Lisa holding Robert at gunpoint and demanding answers about Anna’s murder. Robert, however, claims he was in Afghanistan at the time and shows her footage from his reporting work to back up his story. Lisa struggles to process what she sees and eventually collapses, giving Robert the chance to take the gun and leave. He later returns for his belongings and finds Lisa in tears. Robert reveals that he knows her real name is Lisa Walling and explains that he started investigating her because her detailed novel about Anna’s murder raised suspicions. He decides not to report her, but makes it clear that she must stay away from him and his family.
As Lisa tries to make sense of everything, her memories of Anna begin to change. She no longer sees her sister as the perfect person she once believed her to be. Instead, she recalls their jealousy, arguments, and how their mother always seemed to favour Anna. For the first time, Lisa starts wondering whether she might have killed her own sister. Desperate for answers, she asks Detective Leon Weber whether he thinks she is a murderer, but his silence only leaves her more troubled. Later, she confronts the gardener after hearing him whistle “Somebody That I Used to Know,” the song tied to her trauma. He explains that it had been playing loudly at the villa and hands her the coffee cup she had thrown outside.
Lisa also learns from Norbert that Anna helped her get published but had little faith in her writing, once calling it pretentious. Things take another turn when Lisa discovers that the villa’s security cameras have stopped working. She also spots a discrepancy in the dates on Robert’s reporting footage, casting doubt on his alibi. She calls Yuma over, unaware that Robert is tracking her movements and watching her closely.
The Trap (TV Series 2026) Episode 6 ‘The Truth’ Recap:
The final episode of The Trap (TV Series 2026) sees Lisa finally step outside her villa for the first time in ten years. With Yuma by her side, she visits her parents, hoping to reconnect with them. However, the reunion takes an ugly turn when she learns that Robert has told them about her book and accused her of exploiting Anna’s murder for fame. Lisa insists that she never intended to publish the novel, but she soon leaves after receiving a call about Robert.
The Trap (TV Series 2026) Ending Explained:
Who really killed Anna in ‘The Trap’?
Meanwhile, Norbert visits Lisa’s empty villa and discovers bloodstains, photographs of Robert, and documents containing his address. Lisa tracks Robert down and secretly records their conversation. What follows is a chilling confession where Robert admits that he killed Anna and deliberately used music and drugs during Lisa’s interview to trigger her trauma. His plan was to make her appear unstable on camera and turn her breakdown into a news story.
Robert then explains that he had an affair with Anna for a year before trying to end things when his wife became pregnant again. When Anna threatened to expose their relationship, he lost control and stabbed her repeatedly. Robert tells Lisa that he stabbed Anna six times and claims she delivered the final two blows. When Lisa tries to get away, he shoots her, but Norbert and Pia arrive shortly after. With nowhere left to run, Robert turns the gun on himself.
Did Lisa Konrad really kill her sister Anna?
The ending of The Trap (2026) shows Lisa telling Leon and Narges about the unregistered gun hidden inside the house after she is taken to the police station. Leon privately assures her that he never doubted her. Before leaving, Lisa deletes the recording of Robert and reminds herself that she loves her sister. However, Lisa’s expression in the lift suggests that Robert’s final accusation may have left her questioning her own memories.
Even though she has spent the entire season trying to prove that Robert killed Anna, she still cannot be entirely sure of what happened that night. Her decision to delete the recording of Robert’s confession also adds another layer of uncertainty to the ending. Lisa may finally be trying to move on from the trauma that has consumed her for ten years, but that does not mean she has found all the answers. The ambiguous ending leaves us wondering whether she has finally made peace with Anna’s death or is still struggling with the possibility that she played a part in it.
