After joining together in peculiar fashion, Sang Ho (Jung Kyung Ho of Sorry, I Love You) and his friends form a school gang called The Tigers. As expected, soon a rival gang named East High starts ruffling their feathers. But the real fight is not caused simply by being from rival schools: Sang Ho likes young and attractive Su Hee (Jang Hee Jin of APT), but she is East High leader Jong Seok’s ex-girlfriend, or so he says. Bloody and extremely violent (wait for the finale), Gangster High is a return to form for Park Ki Kyung in a market that is more than doing its job when it comes to demystifying violence amongst teens.
