An excursion boat on Lake Constance. Good-humored passengers celebrate at a costume party. In the middle of it all is Elena Barin on the day before she takes up her post as head of department at the Constance criminal investigation department. She is traveling as a tourist - until the moment she notices a weapon on a passenger.
