The official description of Season 4 states:

“Following the closure of Moordale Secondary, Otis (Butterfield) and Eric (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 – they thought they were progressive but this new college is another level. There’s daily yoga in the communal garden, a strong sustainability vibe and a group of kids who are popular for being… kind?! Viv (Ezeudu) is totally thrown by the college’s student-led, non-competitive approach, while Jackson (Williams-Stirling) is still struggling to get over Cal. Aimee (Wood) tries something new by taking an Art A-Level and Adam (Swindells) grapples with whether mainstream education is for him. Over in the US, Maeve (Mackey) is living her dream at prestigious Wallace University, being taught by cult author Thomas Molloy (Levy). Otis is pining after her, whilst adjusting to not being an only child at home, or the only therapist on campus…”
