Horror writer Gu Yuancheng makes a name for himself by stealing the diary manuscripts of Xiao Bin, the late president of a writers' club, and spying on other writers' ideas. But after publishing "The Death Blade," which he plagiarized from Xiao Bin, bloody knife wounds mysteriously appear on his body. Realizing he may be cursed, he schemes to make Ma Wen, another plagiarist, continue "The Death Blade" and fill in the character for "one," redirecting the curse toward him. Ma Wen eventually falls to his death. Gu Yuancheng's girlfriend, Lin Lan, has actually been getting close to him to uncover the truth behind Xiao Bin's manuscripts. She burns them to let Xiao Bin rest in peace, but she also covets the manuscripts and wants to publish "The Book of Death." Meanwhile, Yin Sha, deputy editor of "Zero Thriller," is none other than Xiao Bin's friend from when he was alive. He has a text message from Xiao Bin, sent just before his death, that reads "Plagiarists die." He watches coldly as the plagiarists suffer the consequences of their own actions, and eventually publishes "Plagiarists Die" in Xiao Bin's name.
