The young, ambitious Eva came to Vienna from Germany to study architecture. At the end of her studies she begins an internship in the office of the influential architect Andreas Hummel. Her everyday life now revolves around designing an art park, and in the process she gets to know the hierarchies of a male-dominated workplace. She observes the dynamics between the architects and gradually becomes part of the subtle power games.

Fun-loving Miri is a genius with numbers. She puts this talent to good use in her job at the town bank in the small village of Hattenstein, where she actively helps her often overburdened boss. When a local winegrower is found dead in a wooded area, she also develops a penchant for detective work. The policeman Nils, one of her old schoolmates, believes it was a sudden heart attack. But Miri's extraordinary powers of deduction tell her that there is something fishy about the case. With the moral support of her ownerless dachshund, Frauchen, she uncovers a large-scale crime in which even the mayor of the town seems to be involved.
