As they staked out the apartment complex where cop-killing criminals were residing, Hong Kong plainclothesmen Mike (Francis Ng) and Brian (Louis Koo) commandeered the flat of an elderly woman (Helena Law Yan) who believed them to be her grandsons. As the watch found them befriending a schoolgirl (Michelle Saram) and a pregnant laundress (Stephanie Lam), there'd be a surprising final confrontation with the crooks, in Wilson Yip's subversive actioner. 92 min. Widescreen; Soundtrack: Cantonese; Subtitles: English; audio commentary; featurettes. In Cantonese with English subtitles.
