Schoolgirl Pauline Niemitz (sixteen) was strangled to death with her own scarf. Overprotective mother Daniela points firmly to Cosima Wüsthoff, gang-leader of classmates who systematically mobbed 'nerd' Pauline. The team also investigates Cosima's claim she saw Pauline enter the car of her stepfather, Patrick Fischer, who has a criminal record, only to find lie after lie and a surprising motive.
