New The Flash Season 2 Finale Extended Trailer Released

Last week's episode of The Flash ended on a down note, as Zoom murdered Barry Allen's biological father, Henry, right before his eyes. To prepare you for tomorrow's season finale, which is titled "The Race of His Life," The CW Television Network has released new extended trailer that is incredibly emotional and reveals the Earth-2 speedster's evil plans.

"I had no idea you were The Flash," Wally West (Keiynan Lonsdale) says to a grief-stricken Barry (Grant Gustin) in the video above. "All that you've done for everyone, now this with your Dad and Zoom, I'm so sorry."

After Zoom (guest star Teddy Sears) reveals his true plan, Barry (Grant Gustin) vows to do whatever it takes to stop him.

The episode was directed by Antonio Negret and written by Aaron Helbing and Todd Helbing.

Now, in Season Two, thanks to Eddie Thawne's sacrifice, Eodard Thawne has been defeated. But Barry was unable to prove that Thawne killed his mother, so his father remains in prison for a crime he didn't commit. And a new ally, Jay Garrick, will arrive with news that the Singularity opened portals to an alternate Earth, with a terrifying new enemy named Zoom now on the horizon.

The cast features Grant Gustin as Barry Allen/The Flash, Candice Patton as Iris West, Danielle Panabaker as Caitlin Snow, Carlos Valdes as Cisco Ramon, Tom Cavanagh as Dr. Harrison Wells, and Jesse L. Martin as Detective Joe West.
