Six years ago, the police received a report and caught some drug addicts. They thought that they were just normal drug addicts but after some investigation, they uncovered a gang.
This gang made and sold drugs.
The police quickly got hold of some evidence, but when they went to arrest them, the other party had already disappeared. They planned for so long but they couldn't even catch a small gangster from the gang.
After this happened, the gang vanished as if they never existed until a few months later. A new case was linked to this gang again.
They managed to catch a person this time, but this person was just someone from the outer ring. He only knew that the boss had a huge background and was really extravagant. The gang had a rigid stratification.
This case became an important case for the police.
The police investigated it fervently and finally managed to find traces of them. During that action, three policemen sacrificed themselves.
