In 1980s Hackney, nine-year-old Akuna's proud father sees him as the next Eddy Grant, but Akuna is asthmatic, and must attend a special school for children with disabilities. Before long, he's fallen foul of sadistic teacher Mr Grimme, who labels him Asthma Boy. Akuna, however, with the help of a cheeky Scots fellow student, soon leads the rest of the class into humiliating Grimme, making Akuna 'King for a Term'.
