In the Line of Duty III marks the film debut of then 20 year old Cynthia Khan starring in the role made popular by Hong Kong superstar Michelle Yeoh in the seminal action film, Corey Yuen Kwai's Yes, Madam [1985]. After casting his new young star, D & B Films house producer Stephen Shin Gei-Yin takes this box office franchise down a harder, more brutal path.

In the opening scene, Ms. Khan has to tear her skirt so she can do some high kicking to subdue a bad guy. She wins over the audience immediately with that move. The movie is non-stop action and features an extended fight sequence between bad guy Stuart Ong and Japanese cop Fujioka Hiroshi, who is wearing handcuffs throughout the scene. Grisly stuff, well done.
