The CW has released a new video going inside tonight's midseason finale episode of The Flash, titled "Running to Stand Still."

The midseason finale, which is also The Flash's Christmas episode, features a trio of rogues – The Trickster, Captain Cold, and the Weather Wizard – all looking to solve their Flash problem, but Patty Spivot has a personal grudge against Weather Wizard, the man who killed her father.

In "Running to Stand Still," when Mark Mardon AKA The Weather Wizard (guest star Liam McIntyre) returns to break Leonard Snart AKA Captain Cold (guest star Wentworth Miller) and James Jesse AKA The Trickster (guest star Mark Hamill) out of Iron Heights, Barry (Grant Gustin) must stop these rogues from taking over Central City during Christmas. Meanwhile, Joe (Jesse L. Martin) and Iris (Candice Patton) meet Wally West (Keiynan Lonsdale).

The Flash airs Tuesdays at 8 p.m. ET on the CW.
