Girl from war-torn 2005 Hong Kong returns to present-day to prevent bombing that will lead to wars by eliminating construction foreman accused of the act. His great-grandfather's spirit intervenes to save him.

San, a girl from war-torn Hong Kong in the future year of 2005, returns to the present day to eliminate Lam-Fung, a construction foreman alleged for setting off a bomb at a groundbreaking ceremony, killing him and his VIP boss. It is prophesied that the bombing's aftermath will lead to future wars; therefore, San's mission is to prevent this from happening. However, the spirit of Fung's great-grandfather wants to save him.—Oliver Chu
