Marcos Tremmer (Benjamín Vicuña), a successful businessman living a peaceful life with his wife Lucía (Adriana Ugarte), receives devastating news: he has a rare, terminal illness and only a few months left to live. Determined to spare Lucía the agonizing pain of watching him slowly suffer and die, Marcos makes the radical decision to keep his diagnosis a secret. Instead of seeking her support, he deliberately fabricates a cold, unfaithful persona and orchestrates an artificial breakup, forcing Lucía to hate and abandon him so she can rebuild her life without mourning his death.
