In Brétema, on the Atlantic coast, there was a time when networks of smuggling, drug trafficking converted, achieved so much influence that they were close to control everything: social power, institutions, the lives of its people. Fins, Leda and Frink explore the coast in search of what the sea throws after a wreck, the sea is for them a place of continual discovery. The fate of these young people will be marked by the shadow odious and fascinating at the same time the ubiquitous Marshall, owner of almost everything in Brétema.

Relato sobre el narcotráfico y las redes de contrabando de la costa atlántica española y sobre cómo acaban por dominar la vida de los pueblos en los que operan. Por otra parte, dos amigos de la infancia y una mujer se dedican a explorar la costa en busca de lo que el mar pueda arrojar, sin saber que su destino quedará inexorablemente ligado al omnipresente y corrupto "capo" gallego que lo controla todo en un pequeño pueblo.
