The Flash Sæson 2 Flash Back
Central Citys kriminaltekniske undersøger Barry Allen er The Flash, resultatet af et mislykket videnskabeligt eksperiment baseret på den supersoniske figur fra DC Comics. Da Barry finder ud af, at ikke alle "metamennesker" bruger deres nye kraft til noget godt, sætter han og hans venner alle deres kræfter ind på at bekæmpe de onde og beskytte de uskyldige.
