After the officers, Harry and Gia took Ahmet for investigation they found out that, Ahmet had paid a sniper to kill the victims so that he would get their property, but he wasn't the one who killed them. He only attempted to do so. The officers didn't believe him so they took his lie detector test, and he was saying the truth.
After doing the investigation from the beginning, they found that the victims were there to meet Hiexon who was their rival in business. When the officers met Heixon, he told them a strange thing that the victims, Serina, Hasmet, and Burak wanted to sell the shares of their company to him but at a really low price.
When they asked Ahmet about it, he said that he doesn't know anything but the officers did not trust him so, they did a private investigation about it and then they found that behind their pharmacy business they used to run a big drug racket without including their step-brother, Ahmet.
But they weren't the mastermind of the racket. They had never met the mastermind in their life so they were meeting the mastermind for the first time, but before they could meet him, they died...
But the officers found something in their phone. It may lead to the murderer...
