Having fallen in love with the same woman who has been in a coma for over 10 years, Yiu Sing Tin and Chong Chin Pang are like rivals. One is a computer game programmer, while the other is a police officer. Tong Ka Ming was initially a police-in-training, but due to trying to help his friend cheat for a test, he was discovered and kicked out of the training campus.
Chin Pang takes this chance to tell Ka Ming that if he wants to become a police officer again, he will need to secretly go undercover and find evidence of the computer hacking crimes that Yiu Sing Tin may be a part of. Things become even more complicated when Kong Kin Yee enters the scene. The more Ka Ming gets involved with these two's disputes, the more unbelievable truths come to light. Things aren't always what they seem to be.
