At a flower club, a gathering of young men and women, they accidentally smoke marijuana out of curiosity. As a result, men cannot escape from the hallucinations and are imprisoned in a prison net or a mental hospital. Vanguard Kwang-suk, Jeong-hee, and Mi-sook are skeptical of their colleagues' misfortunes and smoke marijuana to appease the suffering and wander in search of where to buy them. Min-sook, who has a drug network across the country, kidnaps Mi-sook, who will report him to the police if he doesn't provide free heroin to cover up his crimes.
