25 years ago, a group of female agents went undercover in a five-star hotel in Bangkok to investigate international terrorist, Gu Zhi Jin. An accidental explosion at the hotel killed many of the agents except the leader, Madam Fong, and the target. In present time, Madam Fong meets a group of girls and trains them as her apprentices. She is now on a mission to capture the terrorist she missed 25 years ago.
