Synopsis: By accident, Fan Shuk Heung (Myolie Wu) visits a magical website that lets its visitors barter anything they own exchange for anything they want. Here, you can barter your slender waist for a place at an exclusive school for your younger brother, or exchange your luck for a lover for your dear friend. Fan Shuk is hooked almost immediately. Later on when she suspects that her husband, Koo Ka Yan (Johnson Lee), has a woman outside, she visits the website again to exchange her identity with that of her good friend Hou Yurk Hoi (Selena Li), who has married into a wealthy family. Fan Shuk hopes that Yurk Hoi can help her win back her husband’s love. Yurk Hoi hopes that Fan Shuk can teach her overbearing mother-in-law, Lui Wong (Kiki Sheung), a good lesson. Neither of them has thought that they will become hopelessly addicted to their new identity. By the time they realize how dangerous it will be if they carry on, the magical website has already been removed. The two families get entangled with each other as a result. Ironically, Fan Shuk has an affair with Koo Ka! From then on, every day is filled with both laughter and anger for the two families.
