Nando has taken over the fentanyl truck, he is looking for a distributor, while Joao and Carlitos Miranda look for him. After all there must always be a king.

Nando continues to advance with his plan while Valdés plunges towards defeat. Nando proposes a deal to Gema to bring Muro's fentalin while he begins to doubt Nando's honesty.

After the arrest of a cocaine shipment, Sigüenza and Anxo enter the prison from which Nando has just escaped. Cesáreo tries to help Nando to redirect his life, but his plans are different.

Nando is a young Galician with a simple life. His perseverance leads him to win the amateur boxing contest but his ambition does not stop there, the reunion with his childhood friends leads him to make a series of bad decisions that will change his future forever.

Fearing for his life, Muro self-inflicts injuries in prison. After escaping to the hospital, he forms an alliance with the Albanians. Miranda is pressured by Quesada, the cartel leader. It is revealed that Gema Valdés did not die and is undergoing rehabilitation after months in a coma. Nando proposes to Diosdado to increase their profits by bringing drugs via submarine, but he needs a partner:

The drugs arrive in Galicia in two semi-submersibles, leaving Dani and her new partner, Lieutenant Novoa, powerless. The Diosdado-Joao-Nando triumvirate debuts successfully. In prison, Anxo assassinates Merino on Boza's orders. Muro orders the Albanians to issue a 'search and capture' order for Barreira. Dani is suspended from her duties by Carmo due to the judge Andrade's inaction.

Carmo cold-bloodedly murders Dani after being exposed by her. Confusing him with Nando, the Albanians mistakenly kill Ionut, Cesáreo's new disciple. Unable to fulfill his commitment to Quesada, Muro immolates himself by throwing himself off a cliff. Gathered at the summit with Diosdado, Gema and Joao die in an exchange of gunfire.

With the help of Andrea, a young narco boat manufacturer, Nando facilitates Joao's escape. Muro and the Albanians kidnap Miranda. Gema tries to make a living as an honest citizen, while the 'marriage' of Boza-Merino begins to falter thanks to the cunning of Anxo. Muro swears to Quesada to defend the cartel's interests in Galicia.
