A night-time emergency call from a moving car alerted the police in Carinthia: "Eisner, BKA Vienna, service number 318-12-58. I need support!" A little later, Lieutenant Colonel Moritz Eisner (Harald Krassnitzer) was shot in the head and found motionless behind the wheel of his car in a quarry. When he wakes up in the intensive care unit, he doesn't have the slightest idea what happened. Because he suffers from a "retrograde amnesia", through which the traumatic experience itself is hidden. A fatal consequence of the gunshot wound. After his release from the hospital, he searches in vain in his office for clues to his journey during this weekend vacation.

Moritz Eisner is determined to find out what happened to him. That's why he directs the taxi, which his boss Ernst Rauter (Hubert Kramar) had instructed him to take him home , to Carinthia on the spur of the moment.

Inspector Josef Hudle (Christopher Ammann) found Eisner. But he knows nothing of such a vehicle. When Claudia calls that she is looking for her father, Bibi Fellner immediately suspects where he is and follows him.
Via the cashier of a supermarket, both of them finally come across a first, concrete lead: The woman remembers exactly that Moritz Eisner bought red roses and a bottle of champagne from her and asked for the way to the Kapplerhütte. As Moritz searches the hut, fragments of memories of various scenes come back to him. He also recognizes his hold all standing in a corner
