Martial Angels (2001)

Three years on and Cat's heart still yearns for Ziyang, the fellow thief she met during a heist at a private party which ended with them both in the swimming pool a little richer. Three years later and Cat has a 9-to-5 life in a high technology company when she gets an SOS message from Ziyang: the Russian mafia are holding him hostage after he failed to steal anti-virus software under contract. Cat contacts her fellow light-fingered sisters from the orphanage of their youth and draws up a plan to steal the virus software herself and get her man back ... with just seven days to complete the mission.
