In the future city of Hong Kong, where technology is highly developed, data clerk Lin Xia's life is completely overturned by an unexpectedly captured abnormal code, and she falls into a huge whirlpool of conspiracy.
The calm and restrained security director Jin Chen appears with absolute control and regards her as a useful "tool"; the elegant and gentle young executive Gu Cheng throws out sweet traps in an attempt to include her in the chess game; even the seemingly sunny and enthusiastic maintenance engineer Chen Xing who wanders in the gray area seems to have other agendas.
Under the torrent of data, lies and truth are intertwined, and surveillance is everywhere. Level 3's security alarm hangs high like the Sword of Damocles, the dusty plan code-named "The Ark of the Other Side" hides a shocking secret, and the "Scavenger" is everywhere. Lin Xia has to struggle to survive in the cracks, using his only weapon - the "acuity" that is almost intuitive and the "sincerity" that sticks to the bottom line, to deal with the cold abyss of data and the complex city of people.
She must distinguish who is the hunter and who is the prey. Amidst the deadly traps and cold exploitation, she must find a trace of real warmth and alliance, uncover the truth of the Ark plan, protect everything she cherishes, and prove that in a cold world composed of 0s and 1s, the most primitive "sincerity" may be the most critical code to break the situation.
Purpose: Only sincerity can solve the puzzle between data and people's hearts.
