It starts at the clothing manufacturing site. The new girl, Ah Fong, is lasciviously attacked in the washroom by another woman. Sister Ying steps in to defend her and we see a topless girl fight. Three girls at work become friends and share an apartment together and we learn their back stories all of which are terrible and sad. They have a training sequence together too but it's not kung fu it's just fighting dirty.
Chen Kuan-Tai has a minimal appearance but does fight in the final sequence.
This is one of those movies I find myself watching more to see the fashion and views of Hong Kong in the 1970s. As a martial arts movie it rates just about average for the year and genre but mostly because of the Shaw Brothers production values and the excellent condition of the video.
