As every year, German brewery tycoon Karl Schneibel spends the summer holiday on an Italian island with his beloved grandson Christian, near the children’s home run by his ma, Dr. Gioia. This year however, Christian’s heart isn’t in his summer fling but his lover at home, Anna, daughter of Karl’s general manager Dr. Werner. Christian has a bad eye in Veronica, the woman who became Karl’s much younger lover ‘by travel fate’, the first thing soon proved untrue. But by then, the Schneibel firm and estate have been taken over according to an elaborate conspiracy, which Christian takes on with some help from his friends.
