After watching an online video that mocks a local conspiracy theorist, filmmakers Aaron and Jim decide to make a documentary about him. The man, Terrance G., agrees to show them the various newspaper clippings that he has collected and that he uses to draw connections between significant historical events, including World War I and the September 11 attacks. Impressed with the depth of his research, Aaron begins to sympathize with Terrance, while Jim remains skeptical. During an interview, Terrance becomes agitated and points out a man whom he believes to be following him. Shortly afterward, Terrance disappears without a trace. Worried, Aaron and Jim return to his apartment, which is being cleared out. Aaron manages to salvage the newspaper clippings. When his house is broken into, Aaron moves in with Jim, his wife, and their young child, where he attempts to figure out what each of the newspaper clippings has in common.
