Caronte’s sister Paula gets beaten up by her husband Rodrigo, who then runs off. Despite refusing to do so at first, Paula eventually reports him and Aurelio tells Caronte about what happened. Caronte moves his sister and his niece, Irene, into his home and helps them throughout the reporting process, although Paula comes up against an aggressive judge who refuses to believe her.

Marta manages to release Caronte after convincing judge Araúz that he was simply acting in his sister’s defence, although the lawyer now faces a suspension. Meanwhile, at the courthouse, Marta discovers that Cleo Torres, accused of assisting her sister who was suffering from a degenerative illness to commit suicide, has been left without a lawyer in the middle of her trial.

Caronte is sent to prison, accused of murdering Toni after Paniagua had staged the whole thing to frame him. Marta gets down to work and, with Aurelio’s help, collects different pieces of evidence to convince the judge the commissioner had set it all up. Just when Caronte believed he’d lost all contact with Natalia, his ex reappears in Madrid to talk to him.
