With the border between Austria and Germany running through its waters, Lake Constance provides the setting for a series of murder investigations. Beneath its scenic shores lie crimes with roots in the region's history, local folklore and long-standing rivalries. Working alongside his Austrian colleagues, German detective Micha Oberländer must follow the clues, piece together the circumstances behind each murder and uncover secrets that often reach back generations. Meanwhile, shifting alliances and changing partnerships within the team add their own complications to the investigations.
