Entering the house, she meets Phuong's mother - Ms. Le and Cu Hu (a friend of Phuong and Tam). Son comes to pick Linh up, in the midst of talking, it is revealed that the heart which had been transplanted for Linh is from Phuong - Ms. Le's daughter also Tam's wife.

Son drove away after calling the police to inform the situation. The police named Sau Dung invites him to the police station for a couple of questions. Thinking everything is coming to an end, things are getting weirder as Son claims that when he drove away, Phuong was still alive and was not injured, she was just unconscious. However, the body found by the police was heavily crushed, unable to identify, later Tam confirmed it was Phuong then took her body back home for the funeral.
Cu Hu discovers that Linh's blood type to be O, therefore she couldn't be able to get transplant by Phuong whose blood type is AB. Later, Linh and Cu Hu find a funeral table with the picture of Hong - who is allegedly Tam's business partner. Right after knowing that Hong is missing, Cu Hu drives Linh to the flower farm where Tam is working a night shift.

Phuong says Hong is Tam's mistress and they had much debt due to their failed business. Knowing Tam wouldn't divorce Phuong (Tam truly loves Phuong) and leave her deal with all the debts alone, Hong had secretly texted and told Phuong to go to the abandoned house on Ma Ta Hill in order to know the truth about her husband. Phuong was hiding outside and heard the full story, which little did she know that Tam hits Hong with a shovel later. Phuong terrifyingly ran away while Tam was chasing her. As she was about to get close to the outskirt of the wood, Phuong got hit by Son while carelessly crossing the road. Tam hid until Son drove away, Phuong was still alive and kept warning that she would report this to the police. Tam decided to switch Phuong and Hong's clothes and locked Phuong in the basement, then Tam carried barely conscious Hong to the road where Phuong got hit previously. Tam used Phuong's car to crush Hong until she was completely dead, then made a false statement about Phuong that she was in the accident in which her face was fully crushed. Actually, the heart Linh carries is from Hong. Cu Hu calls the police right away, however, he is hit by Tam, while Linh is chased by Tam in the woods. As she is about to reach the outskirt, Linh suddenly falls like Phuong did. Tam intends to kill Linh but the ghost of Hong shows up to save her. Being terrified to see Hong, Tam is stunned as Hong is staring at him. The police arrive and Tam tries to escape, however, he gets hit by a truck.
