The film follows Barry Allen, portrayed by Ezra Miller, as he travels back in time to save his mother, which leads to an alternate timeline. Although the broader franchise is sometimes referred to as the DC Universe (DCU) in future planning, the movie itself is cataloged within the existing DCEU continuity.
