Vendetta in snowy South Tyrol.

Vengeful Mafiosi, a dead village policeman and secret investigations: In its sixth case, South Tyrol's most popular investigator duo gets to deal with Italy's most dangerous criminals. It is mid-January, in the snow-covered Val Gardena the earth trembles again and again. Around the luxurious winter idyll of S. Cristina, an unusually large number of avalanches are going off. But Commissario Grauner has no eyes for this natural spectacle. Even when a dead man is found in a run-down villa, he investigates only reluctantly. For days his eighteen-year-old daughter Sara has disappeared without a trace. When he learns that his Neapolitan colleague Saltapepe had to go into hiding because the Mafia boss Giorgio Garebani, whom the Ispettore once put in prison, is after him, Grauner no longer believes in coincidence. Together with his wife Alba, he investigates against all the rules - they plunge into a battle that they actually cannot win, but must not lose.
