This movie treats human waste as currency with a completely straight face, which means every joke lands harder because the premise refuses to wink at you. The animation is deliberately ugly in a way that makes the grotesque comedy actually work, it's not trying to be beautiful, so when it gets absurd it commits fully. The action sequences are legitimately chaotic, built on the logic of a world where everyone is fighting over candy made from shit. This is aggressively stupid in the way only a Korean animated film could get away with, which is exactly why it works. If you've ever wanted an action-comedy that refuses to apologize for its central concept, this is the only film that will scratch that itch. By the end you'll have watched people wage war over addictive feces-fuel and felt like you saw something genuinely strange.

In a future where every traditional energy source has run dry, human waste is the only fuel left. The government rewards each bowel movement with Juicybars, addictive candy-like narcotics that drive crime and violence and can sometimes turn users into blue, constipated mutants known as the Diaper Gang. Aachi and Ssipak are two small-time street hoodlums who scrape by dealing Juicybars on the black market. Their luck changes when they meet Beautiful, an aspiring actress whose every trip to the toilet yields a huge haul of Juicybars. Soon the Diaper Gang, the police and others are all after her, and the pair struggle to hold on to their windfall. The result is an outlandish sci-fi action comedy built around its bizarre premise.
