Santuario

In a flashback, Valle and her friends get into trouble when they activate an old train, leading the authorities to move them to an upper sector. In the present, the government decides to interrupt the Sanctuary project and extract the babies; Valle tries to save Pilar and Rocio, but Rocio is disconnected while Valle and Pilar manage to escape with the unexpected help of Victor.

In a flashback, Valle recalls his stormy college relationship with Daniel and Bosco, working on an initial hybrid. In the present, he flees with Pilar, who discovers that her memories are false; after several chases, they manage to escape to Daniel's bunker, while Valle loses the last connection with his father, whose bot is finally erased.

On their risky journey to the bunker, Valle and Pilar traverse a hostile wasteland, facing environmental and assaulting dangers. Once in the bunker, Valle meets up with Silvia and Bosco, who are experimenting with artificial wombs on women. Bosco wants to remove Pilar's uterus to obtain key data, but Valle doubts his intentions.

Valle plans to flee the bunker with Pilar, who still doesn't understand the danger she's in. During the escape, Bosco severely injures Valle, and she uses a code phrase to activate Pilar's defense abilities, who eliminates him and moves on. Valle sacrifices himself so Pilar can survive with her baby, and, once in Sector 6, Pilar downloads Valle's imprint into her mind, starting a new life with her child.
