The prototype of the movie story comes from a long-rumored campus supernatural event at the "Ghost Girl Bridge" of Tunghai University in Taichung: According to legend, a female student was abandoned by a heartless man and jumped into the river at midnight to commit suicide. Since then, the bridge has experienced many supernatural phenomena, so it was named "Ghost Girl Bridge" by students. In 2018, a student went to the Ghost Girl Bridge alone to live broadcast in the early morning. During the broadcast, some netizens suddenly found that there was a woman in white floating in the air on the tree in the background of the live broadcast. At that time, this "ghost live broadcast" incident triggered online discussions. The story of "Ghost Girl Bridge" was extended from this, and it was combined with a series of uninterrupted horror scenes from the audience's first-person perspective, in order to shock the audience all the way to the end, and go straight to the shocking ending!
