Shouyou Hinata, after losing to Kitagawa Daiichi Junior High's setter Tobio Kageyama in his first official volleyball match, transfers to Karasuno High, intent on finally having a proper volleyball team and getting his revenge on Kageyama. Upon arrival at Karasuno, however, Hinata finds out Kageyama has also gone to Karasuno. Initially at odds with each other, the two form an oddball combination and fight together with the other members of the volleyball club. Karasuno reunites with a former rival school, Nekoma High, in a practice match and reignites their school rivalry.
Karasuno High enters the Inter-High Volleyball Tournament and immediately proves they're "flightless crows" no more. After their first match, Karasuno dukes it out against Date Tech High and their famous Iron Wall, which shut down every spike of Karasuno's ace, Asahi, during a previous match. Later, Karasuno fights Aoba Johsai High and seeks to have the same outcome as their first practice match.
After much training, Karasuno again meets Aoba Jouhsai in the Spring Tournament. Though intimidated by Oikawa, the team's renowned setter, Karasuno is determined to do whatever it takes to advance to nationals.
Recap film focusing primarily on the match against Shiratorizawa from the third season.
