Tommy has given himself a new name - Kenny - from the Japanese ken, meaning sword. It’s a good samurai name. A warrior’s name. This summer at camp - a camp for kids who are not wanted at home - Kenny and his friends need all the samurai cunning and strength they can muster. They have declared a war - between themselves and the camp’s sadistic overseer, Matron, and her adult son, Christian, who secretly stalks one of the girls. Covertly building a samurai castle in the woods, Kenny and his motley band of warriors strategize their attack and eventual escape. But then things go horribly wrong.
