Earth-2's Barry and Iris learn the truth behind the events of "The Flash's" last episode and join forces with Cisco, Harry Wells in order to rescue Wells' daughter Jesse and Earth-1 Barry from Zoom's fortress. Luckily for them, Killer Frost isn't feeling warm thoughts for Zoom after seeing her boyfriend killed by the arch-villain, so the evil incarnation of Caitlin Snow joins the team.
"Escape from Earth-2": On Earth-2, the team races to find Zoom’s lair and asks for help from the most unexpected source. Meanwhile, back on Earth-1, Caitlin (Danielle Panabaker) rushes to perfect Velocity-9 so that Jay (guest star Teddy Sears) can stop the Geomancer (guest star Adam Stafford).
Starring Grant Gustin, Candice Patton, Danielle Panabaker, Carlos Valdes, Tom Cavanagh, Jesse L. Martin, Keiynan Lonsdale and Rick Cosnett, "The Flash" airs Tuesdays at 8/7c on The CW.
