The forensic agent found the woman as the light faded from her eyes, a strange familiarity clinging to her lips. Remarkably, she knew the agent’s name: Becca. And the resemblance was uncanny, a mirror held up to the agent's own face. This …

The DNA results compelled Becca's mother to finally reveal the truth. Meanwhile, Becca discovered perplexing photographs within Eugenio's house, a place where her visions grew increasingly intense.

Becca sought out her sister Tamara, a woman who possessed a disconcerting knack for knowing more than she revealed. Humberto offered his assistance to Becca. Meanwhile, Eugenio’s web of deceit thickened with each passing day.

Humberto shared fresh details with Becca, and the encounter culminated in a subtle, undeniable seduction. Meanwhile, under Eugenio's guidance, Tamara’s metamorphosis into her sister, Aleida, commenced.

Aleida relinquished command of her company to Eugenio. Becca directly confronted Dr. Bátiz. Further, astonishing coincidences regarding the triplets’ lives came to light.

Driven by a compelling vision, Becca requests Pilar's permission to explore the hospital's basement. What she discovers there proves profoundly disturbing, and its consequences extend far beyond the initial finding.

The deaths of Beatriz and the disappearance of Tamara have led Becca to believe that Eugenio now poses a threat to her. Consequently, she resolves to place her mother’s safety in the hands of Dr. Bátiz.

With the truth now revealed, the experiment progresses along increasingly enigmatic paths, its boundaries dissolving the distinction between reality and design.
