The demented masterminds behind the cult hit Battlefield Baseball (2003) reteam for this mind-melting companion film set in a nightmarish reform school, where baseball prodigy-turned notorious juvenile delinquent Jubeh Yakyu is forced to compete in a bloody baseball tournament in order to solve the mysterious death of his younger brother, a convicted spree killer. Once upon a time, teenage ball-player Jubeh (thirty-something Tak Sakaguchi reprising his role) was on his way to the major leagues. But when his ferocious fireball pitch claimed the life of his beloved father, Jubed hung up his glove, and turned his back on baseball. His new home now is Pterodactyl Juvenile Reformatory, a dead end hellhole that's filled with cut-throat criminals. With Nazi blood pumping though her stone cold heart, ruthless Headmistress Ishihara presides over Pterodactyl with an iron fist. Meanwhile her cruel servant Ilsa takes sadistic pleasure in the suffering of the inmates. Shortly after learning that his psychotic younger brother Musashi previously perished in this same vile reformatory, Jubed is presented with the option of using his formidable baseball skills to lead Pterodactyl's baseball team The Gauntlets in the national league tournament, or seeing his cellmate Four Eyes (Mari Hoshino) suffer an agonizing death. Now, as the tournament gets underway, and The Gauntlets face off against a series of baseball teams, each more powerful and evil than the last, Jubed fights to stay alive in order to find out whatever became of his long-lost little brother.
