幼稚園教師汪小云在一個晚上出外看戲消遺,看完戲後碰上打劫銀行攜著四千萬贓款逃走的重傷劫匪阿B,她被挾持到夜店,在一間夜店中她和售貨員玲玲等和阿B發生糾纏,阿B後來傷重死去。 小云，玲玲和師姐，在玲玲表姊小倩的指揮下，企圖毀屍滅跡，平分贓款。豈料劫匪同當黨追蹤而至，賊首大哥等對她們企圖先奸後殺，幸得警察把他們及時救出。 在圍捕中，幾經艱險才把全部匪徒逮住，四千萬贓款則在圍捕中被炸藥炸燬了。 Upon entering a 24 hour convenience store, a criminal with a lonesome primary-school teacher as hostage is accidentally killed by her and the youthful attendant in their hilarious struggle to subdue him. The two soon discover a stash of money on the man's person and along with another customer - an attractive model - they decide to cover up any evidence of the man's visit in a pact to split the money between themselves. The group's seemingly full-proof plans are confounded by the vengeful acts of the money's rightful owner and a set of persistent, yet stupid and often comical policeman who hang around 'pursuing' the women.
