A food safety scandal is developing in Stuttgart. Several people are suffering from severe poisoning after eating dairy and meat products from a 'Frisch & Günstig' supermarket, including Schrotti. Almost none of the poisoning incidents are life-threatening, except for Lena Strange. The Frisch & Günstig store manager dies after eating a container of yogurt. And it’s not over. An anonymous blackmailer is threatening to poison more dairy and meat products.
