Preview The Flash season 1, episode 4, “Going Rogue,” with the episode synopsis, promotional stills, and trailer.
Previously on The Flash, geeky, perpetually late CSI Barry Allen was struck by a bolt of lightning that was the result of a freak storm caused by a malfunctioning particle accelerator. After a nine-month coma, Barry awoke to find himself endowed with super speed.
Working alongside scientists Cisco Ramon, Caitlin Snow, and Harrison Wells as well as his surrogate father, Detective Joe West, Barry uses his new-found powers to save people and help contain other meta-humans who also gained powers in the explosion as well as to free his father from a false murder conviction.
The official synopsis for The Flash season 1, episode 4, “Going Rogue,” reads:
“WENTWORTH MILLER GUEST STARS AS DC COMICS’ VILLAIN CAPTAIN COLD; FELICITY FROM “ARROW” CROSSES OVER INTO CENTRAL CITY — The Flash (Grant Gustin) stops a robbery but the culprits get away after shooting a guard, and The Flash chooses to save the man instead of following the criminals. Joe (Jesse L. Martin) shows Barry a book of suspects and Barry identifies Leonard Snart (guest star Wentworth Miller, “Prison Break”) as the leader of the group.
“While investigating the case, Barry gets a surprise visit from an old friend — Felicity Smoak (Emily Bett Rickards, “Arrow”), who heard about his new abilities and came to check them out for herself. She joins him at S.T.A.R. Labs to help stop Snart after it’s revealed that Snart his gotten his hands on a stolen “cold gun,” which could kill The Flash. Dr. Wells (Tom Cavanagh) is furious when he finds out that Cisco (Carlos Valdes) built the cold gun without telling anyone and now it’s missing. Meanwhile, Iris (Candice Patton) is getting the silent treatment from Joe because of her relationship with Eddie (Rick Cosnett). Finally, The Flash and Captain Cold have an epic confrontation. Glen Winter directed the episode written by Goff Johns & Kai Yu Wu (#104).”
