Carmen obtains evidence against the drug-trafficking lawyers, but Judge Ortega thwarts her progress. She tries unsuccessfully to remove him. The drug traffickers exert pressure: harassment, sabotage, and family conflicts. A fatal accident reopens the investigation and complicates everything.

César tries to cover his tracks regarding the narco-submarine while negotiating with the Salaos and Luisa. Rocío frees Rafa, who is being held in the hospital, unleashing a media frenzy. From Madrid, resources are reinforced, and Carmen is urged to close the investigation.

César and the lawyers intensify the pressure on Carmen. She suffers personal and family attacks, but with a new judge, she regains support. Carmen and the police pressure Luisa with a deal to obtain evidence against César.
