SIX TEENS RUN AWAY TO AN ABANDONED FACTORY. THEIR PLAYFUL ACT OF REBELLION TAKES A SERIOUS TURN WHEN THEY FIND A CHILD HIDING FROM THE AUTHORITIES.
On the day before summer vacation, every boy in a firstyear class of a downtown Tokyo middle school disappears. Was it some accident? A mass kidnapping?
Actually, the boys holed themselves up in an abandoned factory on the riverbed. With support from the schoolgirls, the boys start a revolution against the adults from this "liberation zone."
