The entire story originates from a best-selling, award-winning popular computer game: an ace killer who should not exist in this world, the pinnacle of genetic engineering wisdom. No one knows where he was born or where he came from, except for a cold nickname - "Agent 47". But once you've seen him, you will never forget his unique external demeanor, a fatal attraction and a near-elegant cruelty that can only be found in a killer who is a companion of loneliness.
"Agent 47" is a mysterious and complex man, deeply struggling with pain due to the contradictions and denials intertwined within him - although he was cloned through genetic engineering by the largest criminal organization in the world, he was raised by a benevolent church... So for him, perhaps existence itself is a mistake that violates ecological balance. Even though he is talented, charming, and very fascinating, he actually owns very little. A name has even become a luxury, and the only thing that seems to confirm his identity are the two barcode tattoos on the back of his head representing numbers.
Killing is what "Agent 47" has been doing all along. He has never thought it inappropriate to take away other people's lives, and he never reveals personal emotions while working. His unwavering decisiveness makes him look down on everything around him with arrogance as if watching a changing panorama... His life is like a repetitive equation, day after day. However, even the wise cannot grasp the unpredictable fate, and a planned life may also have "accidental probability". "Agent 47" finds that his long-buried morality suddenly starts to become active, and a strange emotional ripple he has never experienced before also arises in his heart - and all these changes happened after he met a mysterious Russian woman.
