Ahead of tonight's episode of The CW's The Flash titled "Plastique", the network has released a trailer featuring footage from the next four episodes, introducing us to Clancy Brown as General Wade Eiling.

This new footage also offers our first look at Robert Knepper as The Clock King, a character who has transferred over from The CW's Arrow, along with a number of new villains that Barry Allen (Grant Gustin) will face over the next few weeks. We also get to see Barry Allen's new training program at S.T.A.R. Labs.

In addition, we also have a scene from tonight's "Plastique", where Eiling reveals to Detective West (Jesse L. Martin) that the government is taking over the bombing investigation, as he demands they turn over all of their evidence. While we don't see her in this episode, this scene teases that the episode's title character Plastique (Kelly Frye) is responsible for the explosion. Take a look at the latest footage before tuning in later tonight.
