The third episode of Tremembe begins with a poignant flashback, revealing the gruesome moment when Anna and Alexandre took the life of Isabella. The family was strolling through a supermarket, accompanied by their two young sons and Isabella. As Alexandre attempted to pay for their groceries, his card was declined, igniting a heated argument between Anna and him over child support and Isabella's presence in their lives. The bickering continued as they made their way home to their apartment, with Isabella attempting to catch Anna's attention amidst the chaos. Anna pushed her away roughly, causing her to bump into something and begin bleeding.

As the couple carried Isabella back to the apartment and laid her on the bed, she cried, joined by their younger son's tears. Anna took the boys to their room and then made her way to Isabella's room. There, she began to strangle her, yelling at her to be silent. Suddenly, Isabella fell silent and motionless. Thinking she was dead, the couple concocted a plan to throw her out of the window and fabricate a story that someone had broken into the apartment and committed the deed.
In the present, the boys find Anna in her room and remark that the door was not locked, leaving Anna perplexed.
Meanwhile, Suzane makes her way into the cage to stay with Sandrao, with Sandrao's gang assisting her in preparing for her interview with Gugu. The warden escorts the team to the interview room, where Gugu begins his questioning. Suzane firmly refutes the notion that she is the mastermind behind it all, asserting that it was a collective idea shared by the brothers. She adds that she and Daniel yearned for freedom and believed that by taking their parents' lives, they could secure their inheritance and move on.
Gugu introduces Sandrao to join Suzane for an interview, where they delve into their intimate bond. As the conversation flows, Suzane is confronted by the inmate who had previously bullied her in her previous prison – Dada, sentenced to 20 years for his involvement in robbery, trafficking, and conspiracy. The encounter takes place right after the interview ends.
Meanwhile, Anna's time off is marred by her children's disdain for her cooking. They insist that their grandmother's meals are superior, and the younger one refuses to accompany her on a walk, fearing that his classmates will believe she'll throw him out the window if he gets poor grades. Anna strives to dispel these myths, while the older child's curiosity about the truth prompts her to consider reaching out to Amaral, the journalist who has been in touch with her. During a family visit, Alexandre eagerly awaits her presence.
Luka receives a release warrant, and Cristian rejoices in the news. They plan to savor every moment together before Luka's departure. Acir continues to pen his tales about the inmates in his notebook, and Lindemberg seeks Pimenta's advice on whether he should share his story of shooting and killing his girlfriend. Pimenta, a fellow inmate and director of a daily newspaper, advises him to tell his own tale rather than let others tell it for him and encourages him to speak with Acir.
Drama unfurls at the men's prison during a family visit. A correctional officer, who has been monitoring Dayse, informs her of Cristian and Luka's romantic entanglement. Enraged, Dayse confronts Cristian by pouring all the food she had brought over him. Cristian tries to soothe her, but the guard seizes the opportunity to lead Dayse outside for a kiss by the prison gate.
Concurrently, Celina sneaks out during her visit with her mother to make out with Daniel. However, Paulina catches her in the act. Celina reveals her fetish for making out with prisoners.
With a heart filled with kindness, Gugu bestowed a gift upon Suzane, incarcerated within the prison walls. The director, however, halted the driver at the gate, engaging in a hushed conversation with Suzane. She imparted a stern message: all incoming items would be confiscated by the authorities, rendering them inaccessible upon her release. Recognizing Suzane's predicament, Odete suggested an alternative route – sending her gifts to Sandrao's residence, where she maintains an address outside the prison's confines.
Meanwhile, Elize's legal counsel returned with news of a film production company's generous offer – a million reis for her story. The only hurdle? Her husband's family, who had learned of her plan to share her tale and promptly sought legal intervention, securing a hearing date. Odete assigned Daniel a new task – customizing a model plane – and in return, he requested a favor. She intervened on his behalf with Paulina, reminding her of Daniel's plight: imprisoned for a crime he committed in defense of his love with Suzane, against his in-laws' disapproval.
As night fell upon Tremembe, the lights dimmed amidst the rainy skies, just moments after Suzane had submitted her college entrance exams to Paulina. Dada and Sandrao engaged in a heated argument over Suzane's fate. Dada voiced his threat to harm Suzane as soon as Sandrao was transferred to an open prison. Suzane confessed her fear of Dada's vengeance upon Sandrao's departure. Sandrao, on the other hand, declared her intention to take over as the prison's unofficial boss upon her release.
The episode concluded with Odete leading the farewell ceremony for Sandrao and the other inmates set to depart Tremembe. As Sandrao left, she and Elize exchanged a nod of understanding and solidarity, their eyes reflecting the shared experiences and unspoken bonds of their journeys within the walls of the prison.
