Sister Street Fighter: Hanging by a Thread

A woman named Birei has vanished in Yokohama, taken by a ring of smugglers who hide diamonds inside the bodies of Chinese prostitutes. Li Koryu (Etsuko Shihomi) crosses the city to find her, working through the nightlife that feeds the operation, and Kazuhiko Yamaguchi keeps the streets grainy and moving. Her older sister (Tamayo Mitsukawa), a jewelry designer, is secretly tied to the same gangsters, so every door Koryu kicks in could lead back to her own family.
