Naked Survival Express

A group of university students on vacation on the Korean coast hire Zhengxi, a former idol dancer, as their guide — until a zombie outbreak tears through their train. Lin Yu notices the mutated zombies only attack people wearing clothes, so the whole group strips naked and starts improvising with plastic wrap and empty bottles. Along the way they pick up Lina, a stranded streaming superstar, jump from the train in a tunnel and hide in a love hotel, where a long-tongued mutant hunts anyone who covers up. When the army turns out to be more dangerous than the zombies, the survivors must cross a slaughterhouse of a port to reach the only boat out.
