'Sex Education' Works Towards a Big Finish in the Full Trailer for the Netflix Favourite's Final Season

How will Sex Education climax? That's the big streaming question for September, when the hit Netflix series returns for its fourth season and also says farewell. How will Otis Milburn (Asa Butterfield, Flux Gourmet) and his friends fare at a new school? What happens when he has a fellow teen sex therapist also giving his peers advice? How stressed is Eric (Ncuti Gatwa, the next Doctor Who) about making a good first impression among his new classmates? What will university in the US bring for Maeve (Emma Mackey, Barbie)? Add those to the queries that'll be answered on Thursday, September 21.

Back in July, Netflix announced two things: that Sex Education would finally drop new episodes this spring, but that this'd be its big finish. Following a teaser trailer at the same time, the platform has now revealed a full sneak peek at how the show will wrap up its roll in streaming's sheets. As always, a whole lot of teen drama and chaos is on its way.

Since 2019, Netflix has taken viewers to the fictional Moordale Secondary School, where Otis followed his sex-therapist mum Jean's (Gillian Anderson, The Great) lead and started helping his schoolmates with their romantic and sexual struggles — as he himself tussled with his own troubles, and also with his feelings for Maeve. When Sex Education unveils its last run, the series will move the action over to Cavendish Sixth Form College. Queue plenty of the trains of thought outlined above, as well as big changes, new beginnings and new challenges.

When Sex Education creator, lead writer and executive producer Laurie Nunn announced that the show was saying goodbye, she said that the series' team "wanted to make a show that would answer some of the questions we all used to have about love, sex, friendship and our bodies. Something that would have helped our inner teenagers feel a little less alone. It's been overwhelming seeing how the show has connected with people around the world, and we hope it's made some of you feel a little less alone, too."

"This was not an easy decision to make, but as the themes and the stories of the new season crystallised, it became clear that it was the right time to graduate," Nunn continued about bringing Sex Education to an end.

As well as Butterfield, Anderson, plus Barbie co-stars Gatwa, Mackey and Connor Swindells, Sex Education will also see Aimee-Lou Wood (Living) back as Aimee and Kedar Williams-Stirling (Small Axe) as Jackson — among other familiar faces.

Helping them say cheerio: Schitt's Creek favourite Dan Levy, Thaddea Graham (Doctor Who), Lisa McGrillis (Last Night in Soho), Marie Reuther (The Kingdom), Jodie Turner Smith (White Noise) and Eshaan Akbar (Spitting Image).
