Min Seo failed to get into college after graduating from high school. He spends the next year cramming for his entrance exam while Jung Hun is a university student fresh out of high school.
Three fresh-out-of-high-school students, Min Seo, Jung Hun, and Eun Young, become the main tragic end suspect after a high school girl died late evening as they went to the same high school as her. Min Seo filmed the girlin an internet cafe without her knowing earlier that day.
All three of these young suspects are 19 years old and are clueless about each other’s presence prior to the tragic end but quickly become fugitives from the law. To clear their names, they work to uncover the truth behind the girl’s death.
