Train to Busan (Walking Naked in Busan)

A sudden Zombie crisis struck the KTX train. Amidst the bloody chaos, Lin Yu horrifiedly discovered that the mutated Zombies were only aggressive toward clothing, allowing those with Naked skin to become invisible. To survive on the brink of death, he was forced to make an absurd proposal to Xia Qing, Chu Yue, and Kim Jung-hee: to abandon their dignity and travel Fully nude. In the carriages filled with corpses, the group searched for supplies naked, with extreme shame and the threat of death intertwining, twisting their already tense relationships into something distorted and ambiguous through a struggle between physical instincts and psychological pressures.
