Laundry entrepreneur Andrea Rossmann finds in a client seniors home the corpse of young Natalie Krämer. Yet manager Immel nor her husband, Alexander Immel, seem to know her. Residents remain discrete, until the team finds she was an 'escort girl' whose clients included retired attorney Klaus von Gemmer. Dementing Henriette Schröder-Bayer claims having seen Natalie's ex, Volker Waldschmitt, from her window the fatal night, with Carola Immel, but her sketch book adds a crucial clue.
