A street party in Bern morphs into a fierce riot one hot summer night when a young man is found beaten to death with a policeman's club. That same Sunday, twenty miles away, an elderly organic farmer turns up dead on his land in the village of Haldiz, drenched with pesticide. Bernese police detective Giuliana Linder and Renzo Donatelli, her younger colleague, are thrown together by the merging of the two murder cases. Is anything really as it seems, or will some new evidence expose an elaborate scam in Haldiz?
