Set in Galicia, Spain, during the 1980s, the series chronicles the transformation of impoverished local fishermen and tobacco smugglers into powerful European cocaine traffickers. Young speedboat pilot Sito Miñanco (Javier Rey) rapidly rises through the ranks of the Galician smuggling clans—alongside figures like Laureano Oubiña (Carlos Blanco) and Manuel Charlín (Antonio Durán)—by forging direct distribution alliances with Colombian cartels. As vast wealth and corruption flood the coastal towns, Sito's personal life unravels: while married to his devoted wife Nieves (Marta Larralde) in Galicia, he begins a passionate, prolonged affair with Camila Reyes (Jana Pérez) in Panama, ultimately abandoning his family as law enforcement, rival clans, and addiction close in on the empire.
