After her girlfriend Lin Wanwan dies despite emergency treatment, Chen Mo receives a WeChat message from her: “Why aren’t you replying to me?” Everyone urges him to accept that it’s just an AI memorial persona, but the account knows secrets they never shared with anyone and gradually leads him to investigate Echo Technology.
