School is back in session, and so is Sex Education — but not for long. The hit Netflix teen dramedy is returning for a fourth and final season to wind down the stories of the Moordale gang.

Except they're not at Moordale any longer. Otis (Asa Butterfield) and Eric (Ncuti Gatwa) now face a new frontier — their first day at Cavendish Sixth Form College. Otis is nervous about setting up his new clinic, whilst Eric is praying they won’t be losers again. But Cavendish is a culture shock for all the Moordale students, who discover the college has yoga in the communal garden, a strong sustainability vibe and a group of kids who are popular for being … kind?! 

Meanwhile, in the U.S., Maeve (Emma Mackey) is living her dream at prestigious Wallace University, being taught by cult author Thomas Molloy (Dan Levy). Otis is pining after her, whilst adjusting to not being an only child at home, or the only therapist on campus.

Sex Education season 4 trailer
