Final year students Sky and Liam's world is turned upside down when they discover they're expecting a baby. Sky desperately wants to finish school, but will she manage to when the baby is due at the same time as her GCSEs? Luke has a troubled relationship with school. His temper can get the better of him and the staff worry whether they can coax him to the end of the year and the GCSEs that will help determine his future. As autumn exam week arrives, Mr Drew hands out performance-enhancing 'brain food' (fruit) to the students and deals with Luke as he walks out of the hall mid-paper. Meanwhile, first-year student Ciaran has an unusual request for headteacher Vic Goddard: he wants time off from lessons to write a novel.
