Lycoris worked as a hostess at a KTV bar. She also worked as an assassin for a syndicate called the Web, taking assignments from police inspector Lau Kin Ming. When Lau ordered her to kill his subordinate Lai—who had discovered the inspector's arrangement with the Web—Lycoris refused and killed Lau instead. Now both the syndicate and Lai's allies are after her. Introduced to Yeung Kwun of the Red Flower Society, she is sent to Bangkok to lie low. There she runs into Zhang Lei, a longtime KTV customer and underworld boss, who is accompanied by Wolf—her childhood friend. Meanwhile, inspector Sam and constable Chase are working the Lau murder case, and the CCTV footage is pointing directly at Lai.
