After their intense victory over Kenma Kozume and the Nekoma team in the Battle of the Garbage Dump, Shoyo Hinata and the rest of the Karasuno High volleyball team advance to the quarterfinals of the national tournament. Their next opponent is Kamomedai High School, a formidable team that boasts an exceptionally skilled player named Korai Hoshiumi. Hoshiumi, like Hinata, is a short player who soars above the net with incredible jumping power and technique, earning him the very same nickname that has always inspired Hinata: the Little Giant. The film adapts the climactic match of the Tokyo Nationals arc, setting up a high-stakes showdown where two players who defy the expectations of their small stature finally face each other on the court. As Karasuno fights to reach the semifinals, Hinata must confront this living embodiment of his ideal as both teams battle fiercely for a spot in the next round.
