The mid-season finale of The Flash airs Tuesday, December 5th and we’ve got a preview.
The episode is called “Don’t Run” and here’s the synopsis via TV Guide:
Amunet kidnaps Caitlin and puts meta-dampener handcuffs on her to keep her from turning into Killer Frost. Amunet tells Caitlin she needs her to perform a tricky medical task and if Caitlin fails, Amunet will kill her. Meanwhile, the Thinker traps the Flash in a speedster-proof prison. With the clock ticking, the team doesn’t have the time or resources to track both Caitlin and Barry, so Iris is forced to choose who to save.
Here’s a preview:
The Flash airs Tuesdays at 8/7c on the CW.
