New Chile Netflix this series is called Chromosome 21. In other words, it’s a Spanish-language production of crime thrillers. The first episode of the series opens with the police being dispatched to a murder scene.
A young man with Down syndrome is found there. They detained him because he was the only person present and had blood on him. The term comes from Chromosome 21, which is extra in people with Down syndrome.
A really uncommon premise for a murder investigation. Thomas (Sebastian Solorza), a young man with Down syndrome, is found covered in blood at a crime scene as the series opens.
When the police approached him and ordered him to raise his hands, he also gripped the metal bar. But don’t be concerned; once they found out he had Down syndrome, his arrest went pretty well. He is also very obedient.
However, it’s more challenging to get him to talk. Not because he cannot, but because the first of many questions to be answered is if PTSD or something else is preventing him from telling what happened.
The judge becomes agitated and demands an announcement from the suspect, Tomás (or Tommy, as he passes). Mariana Enriquezprime murder detective, attends a theater troupe called “Down UP” from the start, and all the cast suffer from Down syndrome.
Valentina Muhr playing Mariana. He was quickly reminded by the instructor, Sofa (Claudia Di Girolamo), that people with Down syndrome have a unique personality.
Just like everybody else. He learned both positive and bad things about Tommy after he started chatting with the other players in the group. as expected when asking about someone. But nothing screamed “killer” or pointed out any mistakes.
Explaining the ending of Chromosome 21: is it a dramatic story?

The final episode of Chromosome 21 explains how the events of the night of the murder are reconstructed. While Beckham waited to arrive, Orlando accompanied Tommy to the factory. Beckham shows up with the loot.
Plus, Zavala was there (unlike Kowalski, who wasn’t, despite Tommy’s muddled claims during police reconstruction). When Orlando started hitting Beckham and looked ready to kill him, Beckham left his fortune and begged Tommy to come back. Tommy kills Orlando by grabbing the gun just in time.
Beckham tried to catch up to Zavala, but Tommy had trouble moving freely. Beckham departs before the police arrive, and Tommy is found in the garage by the police.
The events are difficult to discover for many reasons, including Tommy being reluctant to talk at first because he’s afraid of Zavala, who threatens to kill Tommy and his brother Beckham if he tells authorities the reality.
In addition, Mariana, Durán’s chief investigator partner, who is a corrupt cop and works for Zavala, falsified the evidence presented for the case. Mariana only manages to prove Durán’s corruption at the very end.
Chromosome 21 ends with a public defense explaining what happened during the trial. Durán kills Beckham to keep Zavala safe.
Luckily, Tommy feels safe now and is telling the reality, corroborating Mariana’s evidence detailing what happened and how the presence of corrupt elements compromised the investigation.
In this way, the judge could rule that Tommy had every right to be frightened (Zavala’s hands had reached the police), that he was acting in self-defence, and that he lied out of fear. Therefore, he can’t be held legally responsible for the crime.
The corrupt police officer is taken into custody, and Zavala is sentenced to jail on Chromosome 21. Tommy will not be spending time in jail, but he will be getting special therapy to help him understand serious crimes.
We often see Mariana and Tommy with their daughter Amanda, indicating their relationship with their daughter is getting better. Mariana is a top investigator and appears to be trying to find Tommy.
