Although Olaf runs the quick cleaning business "Fleck weg!" in the small town of Mettmann in the Rhineland, things are all too pure and unsullied for his taste between him and his fiancée Vera at the moment. Because Vera strictly adheres to the main tantric tenet of her house guru Anthony: "Live abstinently for three months and give everything after the wedding." Three young Brazilian women burst into this celibate atmosphere, who are rudely manoeuvred out of a white strike limousine in the middle of the street in front of Olaf's hungry eyes. For purely charitable reasons, the cleaner spontaneously takes in the homeless beauties. Much to the delight of his father Benno, as well as his grandfather, who is as deaf as he is outrageously uninhibited. But how do you explain or hide the presence of the racy South American women to the suspicious fiancée and the other Mettmann gossips? In any case, despite all precautions, erotic chaos soon rages in "Mettmann de Jainero" and the hormones of the provincials dance samba.
