The pressure of secondary school starts to get real for Year 10 Casey, who is dyslexic, a condition that has left her feeling insecure, self-conscious and different. Staff discuss how AI is affecting the school more widely and how they must adapt to this ever-changing, very modern challenge, and a primary teacher is hired to help students with low literacy.

Year seven's Ismaeel, an enthusiastic ball of energy with his sights set on becoming a student representative for his year, canvasses classmates in the school playground, taking his list to school head Mr Burton who agrees to his real passion project - launching a brand-new chess club. Specialist teacher Mrs Burton is determined to help Lewis in year nine, a star student who was diagnosed with autism at the age of eight, come up with inventive ways to build his confidence - including the new chess club. Assistant Head Mrs Delaney-Hudson is determined not to give up on bright and charming year eight student Jacob who struggles to stay put in lessons.
