The naive, innocent Aaw is thrust into the sinful and decadent world of Bangkok go-go bars when she must earn money to pay for her ailing grandmother's medicine. The timid girl, renamed Dau by her new boss Mamasang, soon discovers that pole-dancing isn't her only occupation when a wealthy foreigner (director Spurrier) takes her to his hotel room and helps himself to her virginity. Dau's sympathetic roommate Pookie (Opal) shows her the ropes while diva-ish May (Narisara Sairatanee) and her snarky friends New and Mee develop an instant dislike for the country girl.
Growing jealous of May, Dau begins to use her magic to make herself more desirable. When May sabotages Dau's attempt to become a featured dancer, Dau casts a spell on her that has horrifying results. While continuing to use her powers unwisely, she also manages to inadvertently break the three cardinal rules of witchcraft, leaving her vulnerable to invasion by an evil spirit. When this occurs, Dau is transformed into a vile creature of unspeakable evil who prowls the night feasting on the flesh and blood of her victims. While New and Mee frantically seek the help of a boozed-up old witch doctor to protect them, Pookie tries to cure Dau of her affliction herself but may end up as her next meal instead.

By modern standards, the carnage is relatively restrained and much is suggested rather than explicitly shown. Spurrier isn't out to gut-punch us with gore but would rather give us an extreme case of the creeps, which he succeeds in doing pretty well. Although I've seen scarier Asian fright films that affected me a lot more deeply, the ghost-possessed Dau is a pretty memorable horror character. There are the usual jack-in-the-box jump scares, in addition to several spooky images such as the glowing-eyed Dau floating after a fleeing victim or lurking on a shadowy ceiling like a spider. Spurrier's original score adds to the effectiveness of these scenes.

The DVD from Palisades Tartan Asia Extreme has an aspect ratio of 2.35:1 with Dolby Digital 5.1 and 2.0 stereo sound. Language is the original Thai with English subtitles. Director Spurrier offers an intimate and informative commentary track. There's a very brief "Behind the Scenes" clip, production photos, the theatrical trailer and teaser, and a featurette, "Soi Cowboy Go-Go Bars", in which host Dean Barrett gives us a tour of some of his favorite carnal nightspots. A music video for Underground's awesome end credits song "Rawang" features a slow, sensuous dance by Suangporn Jaturaphut as "Dau", interspersed with scenes from the movie. I prefer the actual end credits version in which the hypnotically gorgeous dance sequence plays uninterrupted.
With its story of a young witch coming to the big city to ply a new trade while learning to develop her supernatural powers (only to find them going distressingly awry), "P" is almost like a shadowy flipside to KIKI'S DELIVERY SERVICE. But more than that, it's also a deliciously dark and erotic visual confection that should have your blood running hot and cold at the same time.
