The Berlin Observatory is facing the financial end. Against the will of the renowned physicist Robert von Reichenbach, the astrologer Lena Moosbach is set, which quickly establishes itself as a crowd puller and fills the empty cash registers of the planetarium. Worried about the scientific reputation of the observatory, Robert spat first poison and bile against the new colleague. But although the sober astronomer rejects horoscopes with the deepest conviction, he falls in love with the charming astrologer. However, when it turns out that she just feigned her Ph.D., Robert feels betrayed.
