Overview
- The tenth season was released on RTL+'s streaming service on May 21, 2026, and will be broadcast in multi-episode blocks on RTL starting Thursday, May 28, 2026.
- Hendrik Duryn reprises his long-running role as teacher Stefan Vollmer and says he feels a deep personal connection to the character while stressing that the role's impulsive behavior differs from himself.
- Season 10 opens with Vollmer having left the profession to run a workshop in Leipzig and being drawn back into the classroom by incidents including a stolen wallet, a rebellious pupil and a neglected class.
- The new episodes feature a supporting cast led by Birte Hanusrichter and Tanja Schleiff alongside younger actors such as Luke Matt Röntgen, Katharina Hirschberg, Acelya Sezer and Leon Ndiaye.
- The revival follows the show's original 2009–2021 run on RTL and its Deutscher Fernsehpreis nomination, and its streaming-first then linear rollout reflects a growing pattern for relaunching established series that could affect how viewers access new German TV seasons.
