The life of forensic scientist Barry Allen (Grant Gustin) went into turbo mode when a particle accelerator explosion triggered a biochemical transformation that made him the fastest man alive. But now he's got to defend Central City from a rogue's gallery of equally superhuman beings and find a way to reverse the singularity brewing overhead. This complete Season 2 collection on six DVDs includes nearly three hours of extras including featurettes, gag reels, the 2015 Comic-Con panel, deleted scenes and more.
