This film essentially begins with a prostitute by the name of "Saengdao" (Piyathida Woramusik) entering a hotel room where she is then savagely murdered and subsequently decapitated by the man inside. A couple of years later, having left Bangkok and needing a place to stay for the night, a Thai rock band just happens to pick that exact same hotel. Upon entering their room one of the band members sees something strange coming out of the air vent and upon examining it further becomes so scared that he runs down into the hotel lobby to escape from what he saw. This strange action is noticed by one of the other members who also decides to look up into the air vent-and he too becomes exceedingly frightened and without saying a word runs away as well. Sensing something is not quite right, each of the other band members examine the air vent and one by one they each see a ghostly image of a woman coming toward them and in abject fear they all run down into the hotel lobby where they quietly discuss what they thought they saw. Not long after that one of these band members sees another apparition in the hotel lobby and upon running outside is killed by an oncoming car. Shocked by everything they have already witnessed the rest of the band then begins to realize that they have all been targeted by a vengeful spirit and each of them look for salvation from it in their own way. Now rather than reveal any more I will just say that this was an interesting ghost film which could have been much better if the director (Tiwa Moeithaisong) had managed to tie up a few of the missing threads in the end. Having failed to do so it leaves the viewer with some unanswered questions and severely marginalizes what could have been an excellent horror movie. That being said, given its limitations I honestly cannot rate this movie any higher than I have. Average.
