Number one hit rock group Berlin Mitte's lead singer Christopher 'Chriz' dutifully sticks to his contract, to remain explicitly single so as not to scare off the countless immature girl fans. Back in his home town between European and American tours, he accidentally bumps into local neighbor girl Lila Lorenz, who doesn't even know the band, unlike her super-fan kid sister Lucy, but catches his attention thoughtlessly advancing him some petty cash. Yet she is rather absorbed by her dentist mother Dr. Angelika Lorenz's nice boyfriend, cab driver would be-vineyard owner Tom. Chriz's manager and bodyguard Horst duly worry as he spends time with Lila, even found in either's bed, the whole band grumbles as he's seen with her, while she is drawn in by kid sister and buddy.
