The 20th season of 'SOKO Wien' has premiered on ZDF, featuring returning cast members Lilian Klebow, Martin Gruber, Andreas Kiendl, Maria Happen, and Max Fischnaller. Notably, Gregor Seberg returns as Helmuth Nowak, taking over as the new team leader after Brigitte Kren's character, Henriette Wolf, retires. The season introduces a new forensic scientist, Max Fischnaller as Julius Rubatsch, bringing fresh charm and South Tyrolean temperament to the team. The season's first episode, 'Vergeltung,' involves the investigation of Werner Novotny's death from apparent carbon monoxide poisoning in his garage. Initial clues suggest foul play, with evidence pointing towards possible manipulation of the gas system and a complex web of alibis. Novotny's wife and former friend have solid alibis, but a second phone found at the scene leads to a crypto-investor, Charly Purtscher, raising questions about motive and connection. The series continues to evolve with a mix of familiar and new characters, amidst a backdrop of changing leadership and ongoing investigations. Meanwhile, the series faces critique, notably regarding Martin Gruber's role in 'Vergeltung,' but remains a staple of Austrian and German crime television. The upcoming episodes are set to explore deeper storylines and character developments, with fans eager to see the new dynamics unfold.
