Elliot

The action begins in 1969 in Madison, Wisconsin. An unknown man murders several people, repeatedly asking if anyone has said "the name" that must not be spoken, and repeating, "Don't talk about it, don't think about it. "
The action then shifts to the present day. Three students—Elliot, his girlfriend Sasha, and his friend John—move from campus into an old house. Soon, strange things begin to happen: Elliot finds coins in his nightstand, which constantly appear there, and a note reading "Don't talk about him, don't think about him" with the name Bye Bye Man.
During a seance involving their friend Kim, this name is accidentally mentioned. Afterward, frightening events begin to happen to the characters: Sasha falls ill with a strange illness, and Elliot and John begin hallucinating. Elliot imagines Sasha cheating on him with John. He breaks up with her to understand who the Bye Bye Man is. He goes to the library and meets you there. You worked there and knew everything, even about this spirit, the Bye Bye Man, directly from your own words.
