The mini budget psycho drama, somewhat based on true story, follows a bunch of adorable high school girls whose casual pastime includes throwing small animals in the air and not catching them on the way down. The leader of the sweethearts is Mizuki (Kaori Kobayashi), who loses whatever traces of sense she might have possessed when her teacher turns up knocked up! The girls form a "miscarriage club" to kill the unborn baby in order to show the insolent adult who calls the shots.
