Barry Allen lived a normal life as a perpetually tardy C.S.I. in the Central City Police Department. Barry’s life changed when the S.T.A.R. Labs Particle Accelerator exploded, creating a dark matter lightning storm that struck Barry, bestowing him with super-speed and making him the fastest man alive — The Flash. But Barry wasn’t the only person who was given extraordinary abilities that night. The dark matter also created meta-humans, many of whom have wreaked havoc on the city. New threats also arrived from parallel earths and dimensional breaches, under the direction of evil speedsters Zoom and Savitar. With the help of his adoptive father, Joe West, his fiancée Iris West, and scientist friends at S.T.A.R Labs, Caitlin Snow, Cisco Ramon and Julian Albert, as well as Harrison Wells from an alternate Earth, Barry races to protect the people of Central City from these powerful threats.
