Heejun is a delivery boy at a Chinese restaurant. While on a delivery, he runs into Sung-yong, his upperclassman in middle school. Heejun and his friend Dong-gi witness Sung-yong’s suspicious behavior and tail him.

Thirsty is about the worst day of Heejun, a delivery man at a Chinese restaurant. Constantly speeding on the streets on his motorcycle, he's always running away from his past and present. The texture of summer dripping sweat makes you suffocate, and the calculative and accurate acting of the characters is so sharp as if it shall cut your skin. The question at the film's end that asks who the true villain is leaves us with serious afterthoughts. (CHOI Eunkyu)
