CID find a man injured on the road, the team rushes the man to the hospital. There, he seems to be mumbling something incoherent. He says that he had done something to a man. CID Struggle to make sense of his statement. Time is running out and they need to act fast. What is this dying man saying? Did he kill someone? Or is it something else?
