Nearing 30 years of age, Frederick Fitzell lives a quiet and well-organised life. He is about to get engaged to his girlfriend. His peaceful existence is turned upside down when he starts having nightmarish visions of Cindy, an old high school flame he hasn’t seen in a very long time. Convinced that something has happened to her and that it has something to do with him, Fred sets out on a strange quest where past, present and future intertwine. Prepare for a narrative tour-de-force and existential questions: Flashback quickly takes you on a sensational rollercoaster that might very well make it the new cult movie of an entire generation.
