Juantxo's life is perfect: He is rich, he has a social position, a career and in five days time he is getting married to the daughter of a marquise. But before that he will grant5 his friends one last request.

At his stag night in a well-known brothel with his two friends - Pako and Konradin - he loses his virginity and his 30-million-peseta engagement ring "up a mulatto girl's ass."

The search for the lost ring plunges the three friends into the underworld of drug baron and brothel king Joao Villambrosa, on whose fat finger the ring now sits.

Undaunted, the trio embark on a furious journeyaround Northern Spain from brothel to brothel, unwittingly setting in motion a series of events that bring the drug gangs to each other's throats.

They are let loose into a bizarre world: From Portuguese mafia boss Souza, his black magic powers and convoy of gun-toting kamikazes to unashamedly corrupt politicians; from dialectic policemen to exotic whores; and from coke, lots of coke, to airbags that inflate with more than just air.

On the way they meet the seductive and dangerous Fatima do Espirito Santo, and the outrageous and unpredictable Pazos, whose efforts to linguistically impress are nothing short of hilarious.

As the chaos and clouds of smoke and coke billow up behind them, Juantxo discovers hitherto untapped powers, Pako's highway credibility and sexual prowess are put to a severe test, and Konradin keeps them both sane with encyclopaedic gems from his store of useless facts.

Meanwhile, many, many miles away, the church bells ring out on a sunlit banquet.
