WENTWORTH MILLER GUEST STARS AS DC COMICS' VILLAIN CAPTAIN COLD

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. Snart revises his plan to steal the Kahndaq Dynasty Diamond and gets a boost when he gets 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.
