Maje leads a double life where she appears as a poor, innocent, and abused wife in public and at home, but at night she attends parties and is promiscuous, having multiple affairs including with a coworker and a man named Daniel. This behavior causes Arturo to become suspicious, leading to fights and eventually him telling her to leave the house after seeing a message from Daniel on her phone.

Maje seduces Salva, a hospital worker in his 40s who is married, and manipulates him emotionally by portraying herself as abused and unloved. She probes him into killing Arturo, using her sociopathic and manipulative tendencies to convince Salva to act on her behalf. Salva eventually confesses to murdering Arturo, initially claiming he acted alone out of jealousy and frustration, but later reveals the full truth of Maje's manipulation.

Police gather evidence through tapped phone calls, surveillance footage, text messages, and witness testimonies that dismantle Maje's claims of innocence and reveal a jointly planned crime. Psychological evaluations and inconsistencies in Salva's story further implicate Maje. Both are arrested and convicted, with Maje sentenced to 22 years and Salva to 17 years in prison, highlighting Maje's psychological manipulation as a decisive factor.

Flashbacks show Maje's double life and promiscuity, while police investigations reveal her as an emotional vampire with sociopathic behaviors who collects and manipulates men for attention or use. She uses claims of abuse to gain sympathy and control, ultimately orchestrating the murder of her husband through Salva.

While serving her sentence, Maje becomes pregnant by another inmate named David, a prisoner convicted of murder. She gives birth under police custody and is transferred to a mother-child unit in prison where she can stay with her baby until the child turns three. Maje and David began their relationship during her previous incarceration.
