Seong Yu-Na

Several months ago, Kang Tae Oh (Park Sang Hoon), a prodigal talent with an IQ of 160, transferred to a new high broadcasting-specializing school...only to find it full of gangs of merciless bullies! He found himself the victim of a gang of violent first-year bullies. But thanks to his fast-thinking abilities, and with the help of some new friends, he managed to not only outwit the first-year student bully gang – but also force them out of the school altogether.

But this is just the start of his campaign against the bullies: After a short period of peace at school, a new, yet more viscous gang forms. Named Dynamite, this gang comprises pitiless second and third-graders who pick on the vulnerable in search of financial gain – and the misery of their victims! This time, Kang Tae Oh’s chief foe is a martial arts practitioner who has somehow managed to land a place in the national squad. Will Kang Tae Oh succeed in outfoxing the bullies the second time around – or could they get the better of him this time?

This movie is the second in the “Kingdom School” series of movies.

“Kingdom School” is a 2021 South Korean movie that was directed by Jang Dong Hyun.
