Synopsis
Barry Allen lived a normal life as a perpetually tardy C.S.I. in the Central City Police Department. But his 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 superspeed and making him the fastest man alive — The Flash. After stopping the Godspeed War last season, it's six months later and Barry and Iris West-Allen are now at the top of their game—both in their careers as superhero and reporter and as a devoted couple. But when the powerful alien Despero unleashes near annihilation on Central City, The Flash and his team—Caitlin Snow / Frost, Meta-Empath Cecile Horton, the light-powered meta Allegra Garcia, brilliant tech-nerd Chester P. Runk and retired detective Joe West—must once again defy impossible odds to save the day. But their victory is short-lived as two new threats rise from the ashes of "Armageddon," one of which will unleash unforeseen horrors into the lives of Barry and his teammates... and change Team Flash forever.
