On his deathbed, a retired forensic lab tech discloses his boss, the chief commissioner's late mentor, forged the evidence based on which Ole Jessen served 20 years for the high-profile murder with his fishing knife on May 1988 Playmate Silke Spieker, if so innocently. Mirko's team gets temporary reinforcement from his ex Samira Vaziri, who competently helps make case it could be true. All traces point to Silke's lover, wheelchair-and mind-locked playboy Anton 'Big Toni' Malik's devoted son Robert Brink and Jimmie Pawletta, for whom she did a scandalous nude photo-shoot.
