Twenty-year-old Leon travels to South Korea to spend a month of the summer with his boisterous older brother Joey, an English teacher who's been living in the country for the past three years.

Leon is thrown headfirst into Joey's world, which mostly consists of smoking and drinking soju with his two housemates, fellow teachers Justin and Frank, both of whom seem to have lost sight of why they ever came to Korea in the first place.

Tensions rise as Frank's detachment from Korean society bubbles into frustration and resentment towards its people, while Leon begins to see an unfamiliar side to his brother.
