The plot describes that the city is full of drug addicts, most of whom are homeless. Sama, the police officer in charge of anti-narcotics, was determined to find Nassar, the source of the drug dealer. After many pursuits, he finally found Nassar who had attempted suicide in his mansion. The arrested Nassar accepted legal sanctions step by step, and Sama was promoted step by step because of the cracking of major cases. In the process, Sama discovered that the reason why Nassar appeared was due to the corruption of the entire social structure. Simply sanctioning a drug dealer cannot solve the root cause. The problem of being unable to stop drug addicts has increased 6.5 times during his career as a police officer working hard to fight against drugs.
