Gangster High is a 2006 South Korean action film written and directed by Park Ki-hyung.

Plot

In 1991, studious soccer enthusiast Sang-ho creates a soccer club called "Tigers" along with his friends Jae-gu and Chang-bae. Through Jae-gu, he meets an attractive, rebellious girl named Su-hee, who turns out to be Jong-suk's girlfriend, leader of a gang called TNT. The two gangs soon become embroiled in intense and violent conflict. When Jae-gu is killed in a car accident related to a gang fight with Jong-suk, the Tigers decide to avenge him. The two gangs meet in a billiards club, and, despite the pleas of Su-hee, a vicious and brutal fight ensues. Three people end up dying, and the rest permanently damaged, including some of Sang-ho's friends. Sang-ho, being the person who started the fight and the only one to walk away relatively unscathed, is charged with the murder of the three people and is sent to prison, where he reminisces upon the fact that the Tiger soccer club was initially created for the enjoyment of soccer and friendship.
