The film grossed HK$72,828 in the first week of release in Hong Kong but quickly dropped in the subsequent month, therefore a box-office bomb.

A team of three CIA officers, including rookie Jack Chen (Daniel Wu), watch through surveillance as an assassin named Fiona Birch (Marit Thoresen) enters the man's heavily guarded apartment suite and, after having sex with him, kills him by breaking his spine with her bare hands during a massage.

As the CIA officers rush over to extricate her from the wreckage, they are shot and killed by a woman in a limousine, leaving Jack as the only survivor.

After six years of gruesome training, only Charlene Ching (Maggie Q), Katt (Anya Wu) and Jing (Jewel Lee) survive and "graduate."

During one of her missions in Hong Kong, Charlene runs into her long-lost mother, Faye Ching (Cheng Pei-pei).

The mission turns out to be Ryuichi's trap to avenge his partner, who was assassinated previously by one of Madam M's girls (Charlene).

Meanwhile, Charlene is in a different temple praying for Katt's soul to rest in peace, and she tells the deity that she wishes to be with the one she truly loves, Jack.
