After transmigrating into a Hong Kong movie world, Su Man becomes an ordinary cadet at Wong Chuk Hang Police Academy. He originally just wanted to get by, but after casually repaying a favor to Brother Ma, he ends up rewriting the deadly plot of A Better Tomorrow: the recording of Tam Shing's betrayal is exposed early, so Brother Ma no longer has to die at Siu Wang's hands.
That one change immediately attracts the attention of the Plane Crime-Fighting System.
"Host interference with a plot character's fate detected. Host successfully helped Brother Ma avoid his original death. Host has officially been added to the list of candidates."
From then on, Su Man's life goes completely off the rails. Solving cases, catching thieves, and fighting crime are just daily routine. The truly outrageous part is that every time he rewrites a movie character's fate, he can copy that character's abilities. Brother Ma's marksmanship, Chan Wing Yan's instincts as an undercover cop, Wong Chi Shing's knack for sniffing out triad activity... All the signature skills of those tough guys in Hong Kong movies end up in his skill bar.
The graduation exam turns into a thousand-person cops-and-robbers game. He takes the campus belle through the fruit market, dodges the military police, and goes head-to-head with a gang boss in Mong Kok. Wong Chi Shing gets stripped down to his underwear by him, then turns around and has to recruit him as an undercover cop. The System's missions get more outrageous by the day: fail, and you get saddled with ten gold-shop robberies, armed with a .38 to take on AK-47s.
"Officer, how come you're so good at fighting?"
Su Man taps his temple. "I don't have money power. Does copying abilities count?"
Starting with rewriting Brother Ma's fate, he's going to change this Hong Kong movie world, one character at a time.
