Operation Black Tide

The robbery of a truck loaded with drugs puts Fernando Barreira in the tough spot of having to answer to Diosdado; Carlitos Miranda decides to change the rules of the game.

Muro fears for his life and harms himself in prison; Quesada, the cartel head, pressurises Miranda; Nando suggests to Diosdado that they must bring drugs via submarine to boost profits.

Nando sets up Joao's escape with the help of Andrea, a young narco boat manufacturer; Muro and the Albanians abduct Miranda; Gema tries to make a living as an honest citizen; Muro vows to Quesada to protect the cartel's interests in Galicia.

Dani and her new partner, Lieutenant Novoa, become powerless as the drugs reach Galicia; Boza commands Anxo to kill Merino; Muro tells the Albanians to issue a search and capture order for Barreira; Carmo suspends Dani from her duties.

Dani faces a deadly threat as she exposes Carmo; the Albanians accidentally kill Cesáreo's new disciple; and Gema and Joao find themselves in the middle of gunfire.
