They come up with a plan to use s*x tapes to blackmail Claudio, but things go badly. Everything reaches its peak in the last episode, which also has a lot of big surprises. As a last resort, Helena kills Claudio to get away from his control because she feels trapped and wants to protect her son so badly.
Unspeakable Sins ending: What led to the murder of Claudio Martinez?
Throughout Unspeakable Sins season 1, Claudio Martinez, the strong and controlling head of the Martinez family, is portrayed as a source of fear and control. His violent treatment of his wife, Helena, and his harsh control over his family members make the environment tense and hopeless.
Here on, fans understand that Claudio has a lot of dark secrets over the course of the season. One of the most important is that he uses secretly recorded s*x tapes to blackmail and control powerful people.
Helena has suffered a lot under Claudio's rule. He threatens her with a video that features her son, Fernando, and his first wife, Cristina, in a bad light. Helena is always afraid that Claudio will release this video and ruin her life, which keeps her in line.
Helena wants to get away from him more and more as time goes on, but she cannot find a way. And that is until she meets Ivan, a young escort, and falls deeply in love with him.
It doesn't take long for their relationship to turn into a dangerous plan to blackmail Claudio with his collection of s*x tapes, which is one of his most dangerous assets. The plan is to make a sex tape of Ivan and Claudio and use it to intimidate the father and get him to leave Helena alone. However, things don't go as planned, and Claudio quickly realizes that someone is playing a joke on him.
Helena finally gives up and decides to kill Claudio as a last-ditch effort to escape his control. She takes matters into her own hands because she cannot stand the thought of losing her son or being manipulated even more.
Claudio's killer plans the murder and waits for the right time, when he is asleep, to sneak into his house and do the worst thing. Helena cannot cut off all ties with Claudio and end the abuse for good if she does this.

The tapes: What happened to them?
From the beginning of Unspeakable Sins, the s*x tapes are an important part of Claudio's power over other people. These tapes show powerful men, like politicians, businessmen, and other important people, having s*xual encounters at Claudio's secret underground parties that are against the law. It is Claudio's way of enticing these men to stay under his control and keep working for him, which gives him power.
In the lead-up to Claudio’s death, viewers see that Helena, who is aware of the tapes’ existence, manages to delete most of them before she murders him. However, some tapes are still there, and their release is still a threat. During the season, one of these last tapes with Helena and Ivan on it gets out.
Even though this scandalous tape hurt Helena's reputation, it has an unexpected effect on how people see her. Instead of destroying her completely, it makes her look like she is manipulated by Claudio, which makes people feel sorry for her.
Are there any other copies of the tapes, though? That is still the question. There are also other questions about who has the remaining footage and what effects it will have on the people involved, even though Helena has erased most of the tapes.
Helena’s actions in Unspeakable Sins: What motivated her?
After years of being hurt and manipulated, Helena is deeply motivated to kill Claudio. Helena doesn't have much freedom because Claudio is controlling and abusive. He abuses both her and Fernando, emotionally and physically.
Even though Helena's relationship with Ivan is risky, it has given her the emotional support she has long sought. It is true that Ivan is not like Claudio, who is not loving, understanding, or kind.
As he is already involved in her life, she is able to stand up for herself and see beyond her pathetic marriage. It becomes clear to Helena that the only way to stop Claudio from controlling her is to do something brave: kill him.
She isn't just trying to get out of a bad relationship; she is also trying to take back control of her life and become independent again. Helena wants to hurt Claudio because she wants to break free from the years of fear and control he has put on her. She also wants to protect her son and herself.
Her actions are extreme, but they are the result of everything she has been through. She thinks they are the only way to make things better for herself and Fernando in the future.

What was Ivan’s role in the murder?
At first, Ivan seems like the most likely person to have killed Claudio. He has been at the scene of the crime, and as the investigation goes on, everything points to him. But there is a lot more to the story than that. Ivan isn't the one who killed the person; he is just one of several people who helped.
Ivan does not kill Claudio directly, but he is very helpful in Helena's plan to hide the crime. She asks Ivan for help after she kills Claudio. Ivan helps by getting rid of the murder weapon, cleaning up the crime scene, and making sure Helena will not find any proof of her involvement.
It is Ivan's love for Helena and his desire to keep her safe that makes him help her. He is more involved in giving her emotional support and helping her deal with the effects of what she did than in actually killing Claudio. Together, they make sure that the police think Claudio's death was caused by betrayal or revenge within the family and not by Helena planning a murder ahead of time.
The final twist: Who was watching them?
Unspeakable Sins ends on a scary cliffhanger that makes people wonder what will happen next. It looks like Helena and Ivan are finally free from Claudio's web of lies and violence after the chaos of the season finale. They decide to start a new life together in Los Angeles, where they feel free and at peace.
However, the dramatic turn comes at the end of the show. As they take it easy in their new home, the camera feed shows that someone is watching them from somewhere else, leaving the audience in suspense. This suggests that the dangers from their past may not be over completely.
This mysterious person could be one of Claudio's friends or enemies who is pressured by the tapes. It could also be someone out for revenge or trying to get back the video that shows them doing wrong things. The camera feed highlights that the lies and secrets from the past have not been forgotten, and there may still be problems that need to be solved before Helena and Ivan can be at peace.
Unspeakable Sins episodes are available to stream on Netflix.
