Hong Kong, Oct 2013. Following a long period of social unrest over bank failures, property speculation and government mismanagement, crowds gather to demonstrate in front of the Legislative Council building. Panic ensues as a bomb is reported inside the LegCo building, planted by someone calling himself "Skywalker". Meanwhile, a branch of Hong Kong & China Banking Corporation is held up by two young people in masks - chemistry student Lang (Kelvin Kwan) and social drop-out Fish (Fish Liew). Among the people in the bank are disillusioned former teacher Yue Chung-tak (Teddy Robin), councilman Ho Chung-lai (K.K. Cheung), his mistress Rebecca (Maggie Chan), the bank's investment saleswoman Luk Wan-yee (Kay Tse), her philandering boyfriend Victor Lo (Wilfred Lau), and Wan-yee's onetime boyfriend, police detective Kin-ho (Paul Wong). All have their own reasons for being in the bank that day.

Tough cop Ken Li (Cheng) is at the top of his game, but he's going to need some help to solve a grisly crime that the offender, a respected police officer, doesn't even remember committing. He seeks out Jack Lai (Lai), a former psychologist now in disgrace and behind bars, who has an uncanny ability to bend people to his will. Making an uneasy truce, this unconventional pair set out on a mission to find the man responsible, a master of hypnotism who will stop at nothing to get his revenge!

When a tough policewoman learns about a group of violent terrorists, she, along with her partner and a Japanese detective, does everything it takes to take them down.
