Taxi driver Tae-gyun receives a call from his younger brother Tae-min. He asks Tae-gyun for help, saying that his car "Thunderbird" was pawned and in it, there is a lot of money that he won from gambling. Now Tae-gyun, who urgently needs money, Tae-min, a gambling addict sitting in a pile of debt, and Mi-young, Tae-min's girlfriend who is a former casino dealer, all go out to get the car back. But nothing goes according to their plan. Towards the end of the night, Tae-gyun decides to ditch them and get the money all alone.

Based on Lim Solah's novel of the same title, Snowball focuses on the friendship between three girls who are united by frustration with the mundane routine of high school life and its associated authority figures, only for their bond to be severed by otherwise different natures.
