Human feces have become the sole source of energy in a city where nature has dried up and died. In order to accumulate this valuable resource, the government distributes “HARD,” which contains an addictive, hallucinatory ingredient that encourages bowel movement. As a result of these HARDs, a small gang of people loses control of their bowels and is expelled from the city for being unproductive members of society. When the residents of the crime-ridden 4th district, Aachi and Ssipak, run into “Ippunyi,” they embark on a reluctant adventure. [AACHI & SSIPAK] sparked controversy for rejecting the naturalistic quality and nostalgia of mainstream animation in South Korea and adopting a vulgar and aggressive no-holds-barred attitude. An insolent and daring animation armed with rough language and a free spirit. (Huh Moon-yung)
