Gasperlmaier doesn't have it easy: A mysterious phone call leads him to Loser, where the bodies of two women become his latest murder case. While Gasperlmaier battles his fear of heights and his weak stomach, he and Dr. Weiss from the Liezen District Police Command face ever more controversial questions.

In this gruesome case, the likeable village policeman, Franz Gasperlmaier, needs particularly strong nerves. The tranquil Aussee summer idyll is disturbed by a terrible discovery in Lake Toplitz. A diver pulls a sawed-off hock from the water. But whose? Luckily, Gasperlmaier's mother-in-law knows the Aussee people very well and already has an idea who's up. The mother-in-law is proven right. The murdered man was last seen at the Altaussee Ski Club's fish dinner. Gasperlmaier and his new wife, Doctor Jolante Roth, suspect the murderer is among the guests. Time is running out, because a second terrible murder follows.

Village policeman Gasperlmaier has a tough time in his third case. He's immediately summoned from a funeral to the bathroom of a family home. There, he finds a dead body. Together with his new superior, the investigation begins. But the first death is followed by a second. More and more pieces of the puzzle are piecing together a grim picture from the past. There's little time left for Gasperlmaier and his new boss, and it seems his mother-in-law is also involved.

Simon Polt (Erwin Steinhauer) is no longer a gendarme. Arrived in retirement, he participates cheerfully in the Weinviertel on village life. When a corpse is found after a feast, his sense of right and wrong again becomes noticeable. The police do not see any third party debt. He sees it differently.

Even Franz Gasperlmaier had never seen anything like this before. He's seen a lot of things, after all, Gasperlmaier has been a police officer in Altaussee for more than twenty years. But a stabbed man on a Monday morning in the festival tent at the Altaussee Kirtag is too much even for a seasoned man like him. And so he makes a wrong decision, not his last one that day, and the dead man sitting in his own blood in the festival tent won't be the only victim.

The latest Gasperlmaier case has almost ended in Ausseerland. On the day of the Pfeiffer's Day, of all days, a young musician is found dead on the Weißenbachalm pasture, and Gasperlmaier must once again embark on a criminal hunt. This time, too, the likeable police officer, Franz Gasperlmaier, can't rest. Not only is his beloved wife, Christine, traveling the world, leaving him alone with the household, but a new murder case is keeping Gasperlmaier on his toes. At the annual Pfeiffer's Day, where he is about to enjoy a fine schnapps with station commander Friedrich Kahlß, a scream shatters the peaceful atmosphere.
