But everyone's got private problems. Häschens girlfriend Valerie is in Sevilla, Max is too shy to go into Berlin's gay-clubs and Ziege is in love with the girlfriend of a manager of a big company. But being very boyish they don't just sell the SexUp pills, but also use them for themselves. Of course the old problems reappear.
