Four new recruits join the newly established police academy's female training program, SKIRTS, with petty competitiveness and infighting ruling the proceedings.

Four new Banshee Squad Members join the Hong Kong Police Academy to undergo training supervised by Madam Wu (Sibelle Hu). Their personalities don't click with the current Squad Members, resulting in petty arguments and duels. However, they later make peace with one another as they join the Tiger Squad Members, supervised by Inspector Kan (Shui-Fan Fung), to undergo new training courses together and combine forces to take down a band of terrorists.—Oliver Chu
