Carnival in Munich. The body of a seventy-year-old man is found on a staircase on the banks of the Isar. A first clue leads to “Irmis Stüberl”, where the man had apparently quarrelled with an “Indian. ” The most important witness of the confrontation is a “Red Riding Hood”, who, however, is clearly too drunk to be questioned that evening. Batic and Leitmayr therefore take it with them at short notice. Silke Weinzierl (Nina Proll), as the “Red Riding Hood” is called, gets very upset the next morning. She obviously slept badly in the drunk cell. No, she doesn’t know the man, and she doesn’t know why he fought with the “Indian. ” And the “Indian”? I don’t know her either. Even though she was making out with him that night. It soon becomes clear: Batic and Leitmayr (Miroslav Nemec and Udo Wachtveitl) are not only dealing with a tricky case, but above all with a very unusual woman . . .
