Fanny Fen-ni

Yan est une jeune chinoise originaire du nord du pays. Elle décide de passer 3 mois (le temps que son visa expire) à Hong Kong. Désireuse de réussir, et voulant gagner le maximum d'argent en un minimum de temps, elle se prostitue, parfois toute la journée. Mais elle garde toujours, dans un coin de la tête, l'espoir secret de retourner un jour chez elle pour y réussir.

Ah Shou (Ye Feng), who appears dimwitted, cleverly outwits a street hawker, Ah Mou (Liu Lu Hua), who befriends him and forms an alliance. Together, they orchestrate various schemes: dining without paying, blackmailing the clients of a brothel, and renting a room to unsuspecting girls but tricking them into thinking the place is haunted, causing them to eventually forfeit their rent. Their mischief continues until they encounter Ah Chiao (Sakura Teng), a vibrant and sharp-witted individual who not only thwarts their schemes but becomes an integral part of their operation. The trio continues with their scams until an unfortunate encounter with robbers and police involvement adds a twist to their adventurous endeavours.
