Inspired by a real life custom from
Thailand, where people would sleep in a coffin for a specific number of
days hoping it would ward away evil and bad luck. A young man and woman
decide to perform the ritual. After that, positive things begin to
happen but later terror sets in. With the help of a professor
specialising in paranormal cases, they set out to exorcise the ghosts
that haunt them, attempting to reverse the wheel of karma.
