Two tactical unit leaders are forced to put aside their differences to help catch a group of robbers.

Kei is the experienced leader of a team of pickpockets — also known as "Sparrows" in HK slang. He enjoys a carefree lifestyle taking photos. One day a dashing beauty, Chun-Lei, suddenly appears in Kei's viewfinder. Kei is mesmerized. But behind Chun-Lei's attractive facade lies a mysterious past and a mission to set herself free.
