"After defeating the Reverse Flash once and for all, the ninth season of THE FLASH picks up one week later following their epic battle, and Barry Allen (Grant Gustin) and Iris West-Allen (Candice Patton) are reconnecting and growing closer than ever before. But when a deadly group of Rogues descend on Central City led by a powerful new threat, The Flash and his team-Caitlin Snow (Danielle Panabaker), Meta-Empath Cecile Horton (Danielle Nicolet), the light-powered meta, Allegra Garcia (Kayla Compton), brilliant tech-nerd Chester P. Runk (Brandon McKnight), and reformed cryogenics thief Mark Blaine (Jon Cor)-must once again defy impossible odds to save the day. But as The Rogues are defeated, a deadly new adversary rises to challenge Barry Allen's heroic legacy. And in their greatest battle yet, Barry and Team Flash will be pushed to their limits, in order to save Central City one last time.
