While camping with his roommate Lin Xiaosheng and others, Sun Shaodong watches Lin touch a coffin used locally to bury those who died unnatural deaths, then take the candle from in front of it. Afterward, Sun Shaodong grows increasingly paranoid. He notices Lin Xiaosheng acting strangely and finds a diary describing "possessing someone to take revenge," leading him to mistakenly believe that the dead Wu Chaoying has possessed Lin. In reality, Lin is using Wu Chaoying's legend to get revenge because Sun won money from him and refused to pay it back. To cover up the secret that he accidentally killed Wu Chaoying two years earlier, Sun tries to kill Lin. But at the last moment, he discovers that Wu Chaoying's vengeful spirit really has possessed Lin.
