When Ji Won-young's direct superior at work is fired due to a corruption scandal, Won-young - in spite of being innocent of any wrongdoing - finds himself unceremoniously discharged from the company as well.
The North Korean defector, who has just settled in the South, is confused by his brother who was separated from the defection process. Ji-hyeok, a Chinese restaurant deliveryman who is having a hard time finding a job due to his criminal record, wants to leave Korea as soon as possible. To raise money for his defector brother, Ji-hyeok, who is involved in a dangerous drug-transport errand, suggests intercepting billions of won of methamphetamine.
