While the official Arrow/The Flash crossover event doesn't happen until the eighth episode for both shows, Arrow's Felicity Smoak (Emily Bett Rickards) pays a visit to Central City in a new trailer for next week's The Flash episode, "Going Rogue", airing Tuesday, October 28 at 8 PM ET on The CW.

Barry (Grant Gustin) must also contend with a new villain named Leonard Snart, a.k.a. Captain Cold, played by Prison Break star Wentworth Miller, whose stolen "cold gun" gives him the ability to literally freeze over anyone and anything he chooses in Central City.

If that wasn't enough, we also have a slew of photos from "Going Rogue", along with the full plot synopsis which you can check out below, along with the trailer:

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.
