Patricia Lam Fung was groomed by Shaw Bros in the late 1950s as the top diva of the studio’s Cantonese division, starring in a series of films with “Sweet Girl” in the Chinese title. This is perhaps the heavy hitter in the line-up, shot in glorious Eastman Color. The film is a genre blender, a campus romance doubling as a crime thriller, with horror elements thrown in, encapsulating the dark side of the seeming innocence of youth.
