Dashing new chief inspector Morey is send to manage the police station of El Príncipe, until then informally run by no-nonsense veteran cop Fran, who privileges his own rules to the Law in order to maintain peace in the drug cartel-ridden quarter.
However, Morey is hiding his real identity as a special agent for Spanish Secret Services CNI. His real goal goes far beyond pacifying the neighborhood. Morey is following a lead that connects the presumably corrupted El Príncipe cops with the jihad.
The CNI has sent the agent to investigate a network of Islamic terrorists that is recruiting among the youngest in the culture-colliding town of Ceuta, where Muslims and Christians coexist like nowhere else in Spain.
Too soon and despite himself, Morey finds himself falling for engaged Muslim teacher Fátima, whom he originally aims to recruit as a confidante. Fátima is local drug baron Faruq's younger sister.
But Fátima is also searching for her missing teenage brother Abdu, who Morey suspects might have been recruited by the jihad. This turns Fátima into a key asset for Morey's investigation, if their hearts don't get in the way.
