Lin Mo, a programmer who has been fired and has only 37 yuan left in his bank account, picks up an orange cat that can talk. Not only does the cat use his Huabei credit account to buy cat food, but it also helps him revise his résumé, teaches him how to handle interviews, and fixes his code. But after Lin Mo joins a new company, he discovers that the sharp-tongued cat is hiding a secret from ten years ago: a missing genius researcher, tampered AI data, and the truth his father has concealed for half his life. The man and the cat join forces to investigate, following the trail from a rented apartment to the company's third basement level. In the end, they must confront a massive scheme to manipulate human minds with AI.
