A group of former criminals who had been encountered by the team in the past - Peek-a-Boo, Weather Witch, and Rag Doll - have banded together and are wreaking havoc on Central City. Calling themselves the "Rogues," the trio are now using their powers for personal gain and causing chaos in the process.

As the team tries to track down the Rogues, they learn that they have someone else on their side - Goldface, a crime boss who has been using his powers of alchemy to help them pull off their latest heist. In exchange, the Rogues agree to steal a valuable serum that Goldface needs.

Barry and the team realize that they need to continue fighting against these villains and all other threats to Central City, no matter what. Meanwhile, Nora is reeling from the fallout of her actions with Thawne and must come to terms with the consequences of her choices.
