God created Man and Man created machines.
Man can question God, so why can't machines question Man?
In 2046, technological advancements keep improving human lives, as well as renewing their desires. So, robots, created to serve man, are born.
The first generation AI android, K-1 (Alex Fong), has just been invented secretly at Tian An Science Lab, with the aim of carrying out dangerous tasks for the police, to safeguard the human law enforcers against injuries and deaths. To test its functionality, commissioner Lin Xiang stations him at a remote town for on job training, putting him under the charge of the local sheriff Xu Da Chun (Hu Jun), with his actual identity a closely guarded secret.
K-1 joins the police force under the assumed name De Ming, immediately cracking various cases effortlessly. With perfect socialising routines, De Ming becomes idolised by the townsfolk in no time, while female cop Su Mei (Sun Li) falls head over heels for him. Xu Da Chun, who's carrying a torch for Su Mei (Sun Li), becomes vexed. He frowns upon their relationship as De Ming is but a robot. The two compete against each other both overtly as well as furtively, often with goofy outcomes.
De Ming and Xu Da Chun are assigned to apprehend a runaway robot K-88 (Wu Jing), which is suspected to have errant AI. After a mind-blowing hi-tech battle involving aerial, underground chases and exchanges, as well as 72 transformations, the invincible K-88 explains his reason for escaping, 'For freedom, not wanting to be a mere robot forever.' He even admonishes De Ming for being an electronic slave.
Xu Da Chun is stupefied. To protect De Ming, and for the sake of human dignity, he engages K-88 without regarding his own life...
Meanwhile, assassination robots, under order to terminate any defectors, are arriving in the town...
