Ventura Nunier is arrested by the Police given they suspect his involvement in the collapse of San Esteban. They have little evidence, however, given he is a wealthy individual and had insurance. Carla becomes concerned that her father will suffer the same fate as Ventura and too be arrested; she tells Marina that the evidence linking her parents to the collapse is contained within one of Teo's watches.
Marina panics, knowing that Nano has the watch, and tries to convince him not to sell it. This gives Nano the idea that they should extort Ventura and Teo for money rather than selling it mainstream. Carla isn't aware initially that Nano is involved in stealing the watch, but begins to suspect that Marina was involved somehow.
Ventura's family are ashamed when he is arrested and only Guzmán visits him in prison. Guzmán uses this as an opportunity to shows support, but to confront Ventura about their current financial situation; it is revealed that Ventura used their wealth to keep the company going and now there is nothing left. Guzmán is aware that this is a lie, however, and reveals that he knows Ventura is addicted to cocaine. Seeing his father devastated, Guzmán decides to keep the addiction a secret and stick by his father.
Marina is put into a tricky situation when Azucena — Ander's mother and the principle of Las Encinas — finds Marina's marijuana in her locker. Azucena plans to tell Marina's mother, Laura, but Marina once again blackmails Martín into convincing Azucena to let it slip. Azucena agrees, but forces Marina to reveal the name of her dealer. Nadia and Ander are furious with Marina when she reveals Omar to be the dealer.
When Marina collapses at Samuel's house, he and Nano take her to the hospital, where they are shocked to learn that she is pregnant. Samuel knows he is not the father, however, when it is revealed she is four weeks along. Nano does not reveal to Samuel, but is aware that the baby is his. Marina considers an abortion but Nano convinces her to run away with him after revealing that their baby would have only a small chance of contracting HIV from his mother.
Samuel becomes obsessed with finding out who is the father of her child, despite the two not being together when she got pregnant. Marina refuses to offer any help in Samuel's search, but takes Nano's word when he insists it isn't him. Samuel's suspicions begin to grow when Marina tries to blackmail Martin again and overhears the two talking about "settling" a problem — Samuel incorrectly assumes the "problem" is the baby.
In retaliation, Samuel attacks Martin believing he is the baby's father. Azucena witnesses and questions the situation, with Samuel remarking that Martin took advantage and got Marina pregnant. Nadia reveals that this is incorrect, however, and reveals the bribe and blackmail between Martin and Lu. Lu is suspended for two months despite denying the situation and Martin is fired immediately.
