Season 1

Undercover agent Javier Morey arrives at El Príncipe’s police station. Right away, he must look into the disappearance of a drug lord’s brother.

A corpse is found and identified as Abdu. The police's inaction around the case makes Morey suspicious. Meanwhile, Faruq has plans for revenge.

Morey thinks Sara is key in the investigation into Abdu's disappearance, but she is warned to stay silent. Fátima has doubts about the wedding.

When Morey's plan proves faulty and Sara is brutally attacked, the agent and Fran's mutual distrust escalates. Fátima’s mother urges her to marry.

After discovering the truth about the corpse found in the sea, Morey reveals his true identity to Fran. Fátima's connection with the agent deepens.

The explosion yields clues about what could be a terrorist cell. Faruq searches for Abdu on his own. Fátima is pressured to end her affair with Morey.

The civic center is sacked, spoiling Morey’s and Fran’s plans. Fátima becomes a suspect, and the CNI is forced to make bold moves.

Morey is pulled from the case, which further blurs the line between his work and his feelings for Fátima. Fran finds out what really happened to his son.

The next terrorist attack is being devised. To frame Omar, Fátima is coerced into learning vital techniques of the CNI from Morey— in a single night.

A dangerous radical leader travels to Ceuta to meet Omar. While Fran gets closer to unmasking the precinct's mole, Morey is kidnapped.

Interrogations take place at the police station. Mysterious robberies make the tension between local gangs intensify — and lead to shocking revelations.

Mati finds incriminating information about one of the officers. Tragedy strikes in Fátima's family — and at the precinct — once again.

It's Fátima's wedding day. Morey is set to leave Ceuta, even with Adbu’s case unsolved. What neither knows, is that a threat is looming.
