Endangered moths, psychopaths with swords and dodgy dance moves. It'd be funny if it weren't so deadly. Joe likes an easy life: messing around with his best friend Simon, dodging his parents and annoying his teachers. All is good, until vicious strangers threaten his school, dragging him into a desperate battle to protect his friends and family. The Frrek have come to purify the whole town, and that means washing the streets with blood. As the violence spirals out of control, Joe is faced with an impossible choice: kill or be killed. Or possibly kill and be killed. It's hard to be sure.
