Germany's only investigating winemaker is back on the hunt for a murderer. A year is coming to an end like none before: the spring frost has destroyed almost all the vines, and just before the grape harvest, a hailstorm wipes out the few ripe grapes. The winemakers fear for their existence. When a body is discovered in a dilapidated cellar and shortly after several women from the village go missing, it dawns on some that the hunt for those responsible for the hail and frost has already begun.
