Socially introverted low-level coder Ben leads a dull, aimless life fixing bugs and staying home every day, with no hope for the future. One late night, his future self travels back in time and shatters his ordinary life. Scarred and worn-out, future Ben returns solely to stop a devastating life disaster: at the AI press conference in three days, his boss will steal his code, his lover will abandon him, and he will become an internet laughingstock, with his life ruined forever. He has only three days to change his fate; otherwise, young Ben will repeat the same tragedy, and future Ben will vanish from the timeline entirely. The two versions of Ben, vastly different in personality and mindset, are forced to live together and team up. They bicker and tease each other while fighting against their ambitious tech tycoon boss Simon. They gradually uncover that behind the plagiarism scheme lies a huge AI trap devouring the labor value of countless grassroots developers. Through struggles and growth, present Ben breaks free from timidity and faces himself bravely, while future Ben lets go of obsession and resentment. In the end, they redeem each other, expose the boss’s plagiarism at the press conference, stage a stunning comeback, regain their career dignity, and rewrite their doomed bleak fate.
