Yaasin, a policeman from Tangier who has almost become an alcoholic, spends most of his time in an exclusive brothel. Several characters arrive in the city at the same time: the millionaire Eric Burns; the German woman Eva Miller who, with her little daughter Gudrun, makes herself a living by doing frauds and small thefts; the smart gangster Rustum Wadi who is looking for a talisman that at that moment is in the hands of Andrews, a homosexual British collector. Yaasin is supposed to protect Burns, but when Andrew's corpse appears the case takes an unexpected turn.
