Nerdy momma's boy Juantxo is engaged to be married. Dragged to a party by his friends Konradin and Paco, he loses the wedding ring inside the body of a prostitute. The ring is found later by Villambrosa, a Mafioso who owns the whorehouses along the north coast. Souza, his rival, instructs his sidekick Fatima to check things out. Juantxo and his friends spend the next three days trying to recover the ring and are soon involved in a gangland war where everyone wears shades and black suits and carries an Uzi.
