Professor Kawato is the new Japanese teacher at the notorious Futagotamaga High School, whose baseball club consists of thugs and bullies who were suspended from all school competitions for a year after causing a brawl during an official match. Now that the suspension has ended, the only remaining club members are interested solely in women, smoking, and doing nothing, until, under Professor Kawato's guidance, they discover a new dream called Koushien. The road to Koushien is far from easy, as they must get back in shape, learn how to play baseball, and win back the mistrust of everyone else, including the principal and other teachers, with only a few months available. Sweating and fighting, the baseball club will find its determination and strength as they proceed towards their dreams, while Kawato's enthusiastic and unconventional ways slowly change the attitude of everyone around them.
