This episode focuses on Harrop Fold School's behaviour team: dynamic duo Mr Chambers and Mr Ben Povey, who's head teacher Drew's younger brother. Cheeky 12-year-old Kayden is well known to the behaviour team and repeated misdemeanours mean Mr Chambers is close to losing his patience with him. Meanwhile, Kayden's long-suffering older sister, Year 11 Shannon, is trying to concentrate on her GCSEs rather than her little brother's antics. Head teacher Mr Drew Povey decides to try a leftfield tactic with 14-year-old Vincent - another boy who's often on the team's books - and puts him on a trial period to join the straight-laced Student Council. And 15-year-old Kim becomes unteachable when her older brother is involved in a serious crime in the community.

The teachers at Harrop Fold grapple with the fun and the friction that social media brings to the school. They struggle to contain a Snapchat revolution when an anonymous school-wide message encourages students to break the rules by coming in in trainers. Meanwhile, head teacher Mr Drew Povey has to try and negotiate peace between Year 11 girls Serena and Lelo when Lelo is accused of breaking the 'girlcode' by talking to a boy on FaceTime. Social media fan Deputy Head Mr Ross Povey tries to motivate 16-year-old Tom, who's studying for his GCSEs, after anxiety problems lead his attendance to drop to an all-time low. And can Miss Bland come to the rescue when 11-year-old Caprice refuses to come to school after being called names on social media? It's also time for The H Factor, Harrop's all singing, all dancing talent competition; will anxious Tom pluck up the courage to perform alongside teacher brothers Ross and Ben Povey?
