Sister Rosetta embarks on a quest to unravel the truth behind Maria's demise, initially casting aspersions on Piquoto, accusing him of the heinous act. In response, Piquoto hurls an insult, branding Rosetta a pervert. Conversations about Maria's murder ripple through the inmate population, as Amparo makes her presence felt in Zurda's unit. She announces that she intends to assume Maria's role and issues an edict to Zurda, compelling her to remit half of her earnings monthly to her. Zurda and Victoria politely but firmly request Amparo to mind her own business. Amparo retaliates with a menacing threat against Zurda's spouse, Lalo, instilling a sense of dread within her.
Marina's path crosses with Alan once more, leading to an intimate encounter between them in the sanctity of the chapel. Meanwhile, Lalo arrives to confer with Zurda and Victoria, recounting how Amparo's henchmen assaulted him and decimated their finances. Lalo cautions them to comply with Amparo's demands, emphasizing that crossing her and her syndicate would spell doom for their venture.
The quintet convenes over lunch, deliberating on Amparo's exploits since her incarceration. They relent and opt for rapprochement with her, acknowledging her formidable danger. Cecilia enters the dining hall and requests Amparo, Zurda, and Gladys to stay behind. She grills the trio about Maria's fate, but the air remains thick with silence. Cecilia then seeks a private audience with Gladys, confiding in her about her diagnosis and pledging unwavering support. She reciprocally requests Gladys to extend the same empathy should she ever require it.
Elsewhere, Yael confides in Gladys his anxieties over the governor's wife's decision to keep Brisa for the entire weekend. Their burgeoning affection finds expression as they share a tender moment, lips locking amidst the prison yard's stark surroundings.
Amparo steps into the realm of adult entertainment, mentoring seasoned stars on crafting enchanting, passionate videos tailored to their clients' desires. Meanwhile, Cecilia finds herself summoned to a confrontation with Andrés, who confronts her about the clandestine adoption ring she has orchestrated from within the prison walls. Cecilia attempts to justify her actions, arguing that she collaborates with inmate mothers-to-be who wish to relinquish their newborns. Andrés clarifies the legality of such endeavors, informing her that he will refrain from taking action against her, provided she can arrange for Brisa's legal adoption. Cecilia frets that Yael would vehemently oppose this plan, but Andrés asserts that she has no other option.
Elsewhere in the prison, Noelia's waters break, plunging her into a maelstrom of fear as she believes Dr. Soriano, Cecilia, and Elba intend to wrest her baby from her arms. Desperate, Noelia seeks refuge with Yael and Alan, only to have Dr. Soriano arrive on the scene. Alan struggles to comprehend Noelia's claims about them stealing her child. As Dr. Soriano and Rosetta proceed with the delivery, Cecilia quietly spirits Noelia's newborn away. To ensure Noelia's cooperation, Dr. Soriano administers a sedative, sending her into a peaceful slumber.
The following day, Marina crosses paths with Coco and Luna. She unburdens herself, recounting how Martin violated her on the fateful night of his demise. Luna and Coco deliberate on how they must substantiate Marina's victimhood at the hands of Martin and his brother, weaving a narrative of justice from the fragments of her ordeal.
Luna entrusts a flash drive, brimming with audio and video files extracted from Martin's phone, into another's care. Meanwhile, Gladys intercepts her daughter, Claudia, imposing a solemn pledge upon her to watch over her brother relentlessly. Elsewhere, Amparo enlists a guard's services for Zurda's protection, sweetening the deal with a generous offer. The guard, appearing unexpectedly at the women's shower, confronts Zurda, insisting on an increased payment for shielding her from Amparo's wrath. Instead, he brutally violates Zurda for her perceived defiance. Noelia awakens from her slumber, her voice echoing with concern for her infant.

Upon her return from a weekend respite at the governor's mansion, Brisa is deposited back into the prison's confines. Cecilia's plea for a private audience with Yael falls on deaf ears, as Yael steadfastly refuses to reprise Brisa's role as a pawn in the governor and his wife's adoption scheme. Cecilia, pulling back the curtain on their ulterior motives, reminds Yael of Brisa's desperate plight, having been deserted at the tender age of five.
Concurrently, Marina tasks Ana with deciphering the flash drive's contents—a treasure trove of audio clips capturing conversations between Dario and Martin, detailing their sinister abuse towards Marina. Interwoven within these audio files are videos, surreptitiously filmed by Dario, depicting Marina and Martin in intimate acts, all without her consent.
Alan's thoughts are consumed by Noelia's haunting words.
