Leo is a part of a team which is named ''The Korean Paranormal Activity'', which visits places that are being described as haunted. Because of the fact that Leo doesn't get scared easily, he has chased tons of spirits. This time, the team is asked to come over at a haunted amusement park because spirits seem to scare visitors away. The team does as what is being asked of them and figures out why spirits don't seem to leave this once so wealthy amusement park, but the spirits don't make it easy on them. Leo challenges the spirits and admits he isn't scared of them, because he is named as the coolest guy the team has. Most spirits seem to accept Leo's challenge, except for one. When it's 4 AM, Leo gets a surprised visit by a spirit named Cha Hakyeon and Hakyeon doesn't let Leo win that easily. In fact, Hakyeon will do everything to win Leo's heart. Leo will be his, whether Hakyeon is a spirit or not. But Leo will do everything to scare off Hakyeon, even if it's going to be his own death...
