Hwanghae plot
"The only thing he must not have crossed."
Gu-nam is a taxi driver in the Yanbian Autonomous Korean Region of China. His wife has left for South Korea and he has huge gambling debts. Then he gets an offer that will cancel his debts. He has to kill someone in South Korea for this. Knowing nothing about his target and hoping to see his wife again, Gu-nam sets off for Seoul. There he is immediately wanted by the police for a murder he did not commit. In addition, a hit man is after him. He'll have to figure out who's trying to trap him in order to save his life or stay out of jail.
