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.
