On a dark road, taxi driver Kyung-chul comes across a scared woman in a broken-down vehicle. He pulls over — but not to help her, only for the woman’s head to be discovered in a local river.

As entering high school, he became friends with Jae-gu, Chang-bae, Kyung-chul, Hong-kyu and Sang-sik. They grouped a soccer team called 'Tiger', building up friendship by playing soccer.
