The Inspector Wears Skirts IV

To save the Hong Kong Police Force's Banshee Squad from becoming defunct, the struggling new squad members seek the help of former officers Amy (Sandra Ng),now a divorced mom with a young kid, and May (Kara Hui),now partially mentally-unstable, to help them with their training regiment, lead by Madame Yang (Cynthia Khan). Their police skills are put to the test when they are ordered to nab a band of brutal thugs in the city.
