Leo, the star center forward of the last World Cup runner-up squad, is at the peak of his career when he is suppressed by capital forces and kicked off Country A's national team on trumped-up charges. His reputation in tatters and career hitting rock bottom, he accepts an offer to join Country C's national team — a side consistently ranked last in the world — taking on the dual roles of head coach and starting center forward. He leads the team through grueling, intensive training to polish their lineup and tactics.
Throughout the World Cup campaign, he guides the team past biased refereeing and off-field dirty tricks. They defeat Country A in the knockout stage to settle the score, then overcome the defending champions Country B. In the end, he leads this widely written-off underdog team to a miraculous championship, and lifts the World Cup trophy with his own hands.
