A short fan film that bridges the DCAU (Young Justice mainly) and DCCU, a "what if" story where the Flash visits Bart Allen first, rather than Bruce Wayne, to help prevent Superman from taking over Earth.
There's a mystery afoot in Gotham City, and Batman must go toe-to-toe with a mysterious vigilante, who goes by the name of Red Hood. Subsequently, old wounds reopen and old, once buried memories come into the light.
