The video is a summary of the movie "Nightmare Teacher." The story revolves around a girl named Dodo, who wishes to be prettier than her classmate, Cheon. One day, she receives a mysterious message with a link to download an app called "My Perfect Camera." The app grants her wish, making her the most attractive person in the world.
As Dodo becomes popular, she starts receiving attention from her classmates, including her ex-boyfriend, John Suk. However, she soon realizes that John only wants to be with her because of her newfound beauty.
Dodo discovers that the app was sent to her by the school's director, Chull, who has been sending the trial version to students who are insecure about their physical appearance. Chull reveals that he is not the creator of the app but is responsible for distributing it.
To buy the full version, Dodo must prick her finger with a needle, which leads to her signing a contract with a mysterious entity. It is later revealed that the entity is the "horned man," and Dodo's soul is trapped in a mirror forever.
