A life on Sylt? A dream! At least for the retired couple Frieda and Ernst Schmälzle. However, since their savings are not enough for a thatched cottage, they settle down with their spaetzle press and dachshund Gustav at the Kampen campsite. But between the communal shower and the chemical toilet, conflicts simmer, and the Schmälzles' marriage begins to face serious troubles – until a neighboring camper is found murdered, and Frieda must prove her husband's innocence. A hilarious detective duo amidst beach houses, caravans, and the whiskey mile.
