When Mr Bennett, Head Teacher of Trenwith High School, dies in mysterious circumstances, suspicion falls on 18 year old JOE MERCER. Joe is the epitome of a young hooligan-permanently excluded from Trenwith High School, always hiding behind his hoodie, except for when he's hooning around on his motor bike. Then it's his full-face helmet that provides his camouflage. But did he really do it? His best friends, SEB HOWELL, whose smile can make girls lose their balance, and Seb's girlfriend EMILY BENNETT, the head teacher's daughter, think not and set out to prove him innocent.
