Until recently, 26 year-old Barry Allen, lived a normal life as a C.S.I. in the Central City Police department. Then the S.T.A.R. Labs Particle Accelerator exploded, bestowing him with superspeed and making him the fastest man alive. With the help of his scientist friends at S.T.A.R Labs, Barry began a journey as The Flash. When the team and Barry were finally able to defeat the The Reverse Flash, a Singularity was ripped in space. After closing the Singularity, Barry thinks he's seen the worst. But the arrival of Jay Garrick reveals the Singularity actually opened portals to an alternate Earth, known as Earth-2, which is being terrorized by an evil speedster named Zoom, who sends an army to Earth-1 to defeat Barry. Just as Barry finds solace in his father, Henry Allen, who was freed from a wrongful life sentence, Zoom kills Henry before Barry's eyes, his newfound stability is shattered.
