Two schoolboys who have just discovered a mutual attraction are witnesses to the murder of three gang members. Although Jan and Lukas are seen, they are able to flee, but the fear of being found by the murderer starts to weigh heavily on them. The local police chief Helen (Nicolette Krebitz) is investigating the case, along with her Munich colleague Corinna and her new boss Roman Berg. In a mix of fear and embarrassment, the teenagers hope that staying silent will keep them alive.
One day Nino Sorrentino appears at the winery, an old friend of the landowner Matteo DeCanin. But Nino is more than a companion from Matteo's childhood days. He is part of Matteo's dark past, which took its fateful course in Naples. At the same time, a bad incident shook the idyllic life in the area: At night, a young woman was hit by a car on a mountain pass. Carabinieri Adrin Erlacher immediately takes over the investigation. Department head Christina Melauer wants to put the case aside, but the evidence piles up for the Carabinieri - especially when he finds the wine label for a 3000 euro wine among the evidence. The honest law enforcement officer investigates on his own. Winemaker Matteo is also the focus of his investigations.
