Commissioners Xavi Bonet and Fina Valent examie the death of diver Tomas Vallin, a young geologist stung by a swarm of poisonous jellyfish, out of season and an overdose, injected. Tomás was recently fired by the geological institute's director, Enric Gutiérrez, while his girl friend Catalina is missing ever since. Pursued by the murders, Catalina managed to flee and seek shelter with her ex, encironmentalist aktivisten Eduardo Montez, ignoring he's being blackmailed. Xavi's investigation digs into a ruthless network of politics, business and corrupt politics, probably linking his mayor father Baptiste to organized crime trough businesswoman Isabella Gutiérrez and ultimately the city's crime king El Tauró.Meanwhile Xavi is pressured trough his gay lover and Fina's teen brat María wants to live with a 'lover boy' pimp.
