Margareta Sommerfeld is annoyed: She has been persuaded by her mother to go on a coffee trip. Now she is sitting in a bus filled with euphoric retirees, lowering the average age. But she is not alone: the handsome Simon von Brehden also doesn't quite fit into the cheerful travel group. Margareta is visibly taken with him, but before they can get closer, she discovers his corpse in the heating cellar of his villa.
