Maki Sakai plays Teppen, 25, a denizen of a Hong Kong slum who supports herself by snatching the designer shopping bags of Japanese tourists.
Sakai portrays a "rough around the edges" but highly intelligent and ambitious young woman, who meets up with Naoki Hosaka, a corporate vice president whose uncle owns the company. They meet when he connives to evict her grandmother and friends from the back alley barracks land that his company is so eager to take over.
When her grandmother collapses during the eviction, she confesses she found Teppen on the street as a baby and her real mother is a Japanese woman who has written her Japanese name on a necklace--a modern day equivalent of the "omamori" amulets of Edo period samurai dramas.
