Murder, manslaughter, or paranoia? The "powerhouse," a single woman of our time, navigates through love adventures and career disasters. Full-figured and sharp-tongued, she tackles her challenges without letting real or imagined catastrophes get her down. However, in light of strange deaths occurring in her daily life, the otherwise tough former girl-next-door gradually begins to doubt her sanity: an ex-lover is found impaled, and the next day, an unpleasant neighbor falls down the stairs during the cleaning week. Murder, manslaughter, or paranoia? The manageable world of the Swabian provincial capital suddenly appears in a new, murderous light.
