The direction from where that car was coming it was just a forest area and she went to that forest but she can't find anything there and she saw a lake deep inside that forest and she went there and she saw a car there hidden in bushes. She saw it the same car as they gave found and it had same number late as well. She open the door and look inside but she didn't find anything there. The number plate was fake so they can't identify the car. But while checking the photo of the cars then Sia saw something and there was a doll hang on the car that they found near lake and she went to get that doll as it the only difference between that cars. She take that doll and look at it but it look like just a normal doll of a Pinocchio. But she saw it was sewed from back in very even way. So she cut the thread and open it. She saw a pen drive inside it. So she went to play that video and she play it and it was a voice recording where that person talk about the drug dealer, Yeon. That person say that he is a delivery man of Yeon but recently there has been news spreading among them that there is a mole in their gang so Yeon is killing whoever he think is mole so many people are leaving their fang or some went underground so he left that car there and Yeon always gave a two car same so it would be easier for them to identify each other. Lastly, he say Yeon might collab with international dealers and might kill all of his man but the recording stop in that and Sia think what might have happened. There was no one in the office so she to her chief office first and told him about all that recording and say she will go to arrest Yeon. But Chief say to stop for a moment and they will think about it later but Sia say she have to find him and went out if the office and her Chief say she never listen to me. She went to a bar where Yeon supply the drug and she had call her members so they were already waiting outside the bar. She say let's go and they all went inside and they caught the suppliers there and bring them to station.
