The Flash's mid-season premiere synopsis is out.
Episode 10 is titled, Revenge Of The Rogues and will air on January 20th at 8 pm on the CW.
Prison Break stars Wentworth Miller and Dominic Purcell will guest star as Captain Cold and Heat Wave and challenge the Flash to an epic battle.
The official synopsis reads as follows (via Comicbook.com)
Leonard Snart AKA Captain Cold (guest star Wentworth Miller) returns to Central City with a new hotheaded partner in tow – Mick Rory AKA Heat Wave (guest star Dominic Purcell). The duo plan to steal a multi-million dollar painting, but Cold has another agenda while in town – to set a trap for The Flash. Snart and Mick kidnap someone close to The Flash and threaten to kill them unless The Flash shows up for a battle of fire and ice. Barry tells Joe (Jesse L. Martin) he isn't sure he should take on Snart again after the casualties that happened the last time they fought. Meanwhile, Barry asks Dr. Wells (Tom Cavanagh), Caitlin (Danielle Panabaker) and Cisco (Carlos Valdes) to help him double his training efforts so he's ready for the Reverse Flash when he returns to Central City. Iris (Candice Patton) deals with the aftermath of Barry's confession, and Cisco makes the CCPD a new shield. Nick Copus directed the episode written by Geoff Johns & Kai Yu Wu.
The winter finale suggested that Harrison Wells is in fact the Reverse Flash.
The fall premiere will look at Barry Allen feeling defeated after what happened with the Reverse Flash, and he also has to deal with the aftermath of what he told Iris.
