Fai (Intira Charoenpura) is a girl who's mysteriously connected to the number "6", which is related to her bad luck. On the night before her 24th birthday (2+4 = 6) , her friends come to celebrate. Ong (Watcharachai Sataphitak), one of her friend who has the knowledge of horoscope finds the snake star in the sky, which rarely appears in rainy season. It's the sign of bad luck that could claim their lifes, but Khan (Ray Macdonald) insists to everyone that's absolutely nonsense and wants to prove the truth.
Following Khan's belief, all 6 friends head to a desolate mansion that has been told about 6 coffins lying somewhere in the mantion. They come face to face with supernatural events that come along with their ultimate fear.(http://www.dvdasian.com)
