Six different sets of characters. Only two of these plot strands run (roughly) from beginning to end, and they seem to concern - 1) a couple from the underworld, who come up to modern HK to suck life-force from brutally killing them 2) another couple, May (a nurse) and Philip (a cop) who, because of their dates of birth, have the power to defeat the bad guys. Along the way, we see sex on a motorbike and in a deserted disco, a few shower scenes, a couple of guys going to a brothelette and tongue-bathing the pros, a silly fat guy swordfighting someone he calls master, Yukari Oshima looking totally lost as a spirit doctor, Mark Cheng wandering around with no idea and partnered by Woo Fung.
