A futuristic research compound develops a new police tool called the Power Glove. Supposedly, it gives the wearer incredible powers by letting him tap into the 'unused 80%' of his mental potential. It turns out that the glove also enables the wearer to take over the minds of others, and one unbalanced police volunteer tries to use this to stage a coup. In the end, one of the three test cops is killed, another survives to stay on the force, and the rogue cop makes his escape. 20 years later, the dead officer's son gives away his identity by using his father's personal martial arts technique in a fighting competition, thus drawing the attention of both the remaining good and evil supercops. The kids and the old guys must then start getting ready for a multi-generational final battle of good vs. evil.

A young Chinese Security Officer, Darren, is called for Team 808, which fights against the smuggling of drugs and corruption...

Frustrated in his attempts to assassinate Yee, who is an important official in Japanese-ruled Shanghai, Old Wu, who has lost his wife and two sons as well as two women who had attempted to seduce Yee, now recruits Kuang, Mai Tai Tai, and their troupe of drama students from Hong Kong University in yet another attempt to do away with Yee. Mai Tai Tai is chosen to befriend Yee, which she does by posing as the wife of Mak, befriending Yee's wife and her female friends, and then eventually befriending Yee himself. Even though both get together, they do end up going separate ways, only to meet again four years later. This time Mai is all set to entrap Yee at Chandni Chowk Jewellers which is owned by an East Indian man named Khalid Saiduddin. The question does remain: Will she and her troupe succeed?
