Invisible Target  (DVD English)

An armoured truck carrying $100 million of cash is attacked by a criminal gang which calls themselves the "Ronin Gang" with explosives as it stops at a traffic junction in front of a jewellery shop. All the security guards were shot dead except one, while responding police officers suffered serious casualties under the gunfire of the heavily armed gang members. The explosions also killed several civilians, including a lady in the shop. Six months later, the same gang reappears in Hong Kong, injuring a group of policemen, two critically, during a spot check. The dead woman in the jewellery shop was CID detective Chan Chun's fiance, while the injured policeman are led by Trainee Inspector Fong Yik-wei. Both officers vow revenge on the criminal gang.
