Rule Number One
第一誡
Synopsis
Rookie Sergeant Lee is injured in a shoot-out and is assigned to the dubious-sounding Miscellaneous Affairs Department (MAD). There, he is paired up with Inspector Wong, a jaded and alcoholic veteran who explains that MAD’s role is to answer supernatural calls. Wong explains MAD’s rule number one - there are no ghosts. For every seemingly inexplicable phenomenon, there is a corresponding scientific and rational explanation.
