Pregnant Lady Nak dies giving birth in 1868, returns as a ghost and has her restless spirit trapped in a pot by a clergyman (with help from her husband). Cut to present day and things may end up repeating themselves with reincarnated characters. Leading lady Trirak Rakkarndee had already starred in a Mae Nak TV series in 1989 prior to appearing in this film version (one of dozens about this same ghost).
