Three best friends accidentally discover a tropical plant which is actually all-powerful aphrodisiac.The effects of this plant’s juices are amazing: people end up making passionate love with a first person they see and all the brakes cut loose instantly!

Ziege, Häschen and Max have now moved to Berlin for studying. They ain't got no money till the mystic plant reappears. Soon they have enough money for champagne, a penthouse and a nice car. 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.

They're young. They're hungry for life. And they've left the cold, gray North behind for fun and adventure on a Mediterranean island. Elisa: rich, spoiled, fleeing from daddy and his stifling upper-class morals. Richie: the sexy drifter for whom every woman is a potential meal ticket; Florian: sensitive, gentle, the type not only girls gravitate to; Daniel: stuck between adolescence and small-mindedness. But even in paradise there are some dark corners that never get any sun. It's where you can lose your way, or your bearings... where you can discover love or refuse to see it... where you realize that you haven't really left the cold, gray North behind – but that it's inside you - and that this is real life...
