Professor Kawato is the new Japanese teacher in the ill-famed Futagotamaga high shool, whose baseball club is composed by thugs and bullies who have been suspended for a year from all school competitions for causing a brawl during an official match. Now that the suspension is over, the only club's members left are interested only 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 have to get back in shape, to learn how to play baseball and to win everyone else mistrust, including the principal's and other professor's one, with only a few months available. Sweating and fighting, the baseball club will find his determination and strength, as they proceed towards their dreams, while Kawato's enthusiastic and non-conventional ways slowly change the attitude of everyone near them.
