Carmen investigates the Salaos family and the narco-lawyers, which creates new enemies for her. César, under investigation, allies himself with Sotelo and Setién. Together they pressure authorities to stop Carmen, implicating all of Marbella's criminal elements without getting their own hands dirty.

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.
