Barry Allen (series star GRANT GUSTIN) lived a normal life as a perpetually tardy C.S.I. in the Central City Police Department. Barry's life changed forever 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. After a thrilling cliffhanger last season which saw the new Mirror Master (series regular EFRAT DOR) victorious and still-at-large in Central City, The Flash must regroup in order to stop her and find a way to make contact with his missing wife, Iris West-Allen (series star CANDICE PATTON).With help from the rest of Team Flash, which includes superheroes Caitlin Snow (series star DANIELLE PANABAKER), Cisco Ramon (series star CARLOS VALDES), and Nash Wells (series star TO M CAVANAGH), as well as the Flash's adoptive father Joe West (series star JESSE L. MARTIN), Meta-Attorney Cecile Horton (series star DANIELLE NICOLET), tough cub reporter Allegra Garcia (new series regular KAYLA COMPTON) and brilliant tech-nerd Chester P. Runk (new series regular BRANDON McKNIGHT), Flash will ultimately defeat Mirror Master. But in doing so, he'll also unleash an even more powerful and devastating threat on Central City: one that threatens to tear his team - and his marriage - apart.
