The Flash

A new big bad is introduced to Team Flash and friends and foes, old and new, begin to descend upon Central City in the season premiere.

Barry feels guilty for what happened to Caitlin. Mark hatches a plan that makes everyone skeptical. Red Death looms in Central City and commands that failure is not an option.

Barry and Iris believe they know what the Rogues are after. Team Flash recruits unlikely allies to help. Allegra does her best to avoid having a conversation with Chester.

With the power out in the city, Team Flash calls upon the Rogue Squad to help as Iris is visited by an old friend. Joe and Cecile work on finding a balance.

As the Red Death wreaks havoc on Central City, Barry and Iris come up with a plan and turn to Cecile for help. Barry is faced with his greatest mistake.

Iris is alarmed by Barry's disappearance and Cecile assures her everything will be ok, but does she know that for certain? Team Flash is affected by a mysterious substance.
