City Horror: The Evil Spirit

The Evil Spirit: When Cha returns to her hometown to film a documentary, she finds that many of her friends are married, and many others that were married have already died due to unconfirmed accidents. Cha reaches back into her memory and recalls a girl named Yah, whom Cha and her friends made fun of when they were young. Yah had been killed in a fire, which Cha's friends were to blame. Could it be possible that Yah has returned from the dead to seek revenge? Or perhaps...Yah may have never died in the first place?
