The Flash Episode 17 Sneak Preview: Tricksters

After the "Rogue Time" episode of The Flash, The CW released a sneak preview of next week's episode, which is called "Tricksters."

In "Tricksters," a copycat killer who goes by the name "The Trickster" (guest star Devon Graye) starts setting off bombs in Central City. In order to stop the villain, Barry (Grant Gustin) and Joe (Jesse L. Martin) meet with the original Trickster, a criminal mastermind named James Jesse (guest star Mark Hamill), who has been imprisoned for 20 years. Things quickly go from bad to worse when the Tricksters unite and take Henry (John Wesley Shipp) prisoner. Meanwhile, Iris (Candice Patton) asks Eddie (Rick Cosnett) for help with a case, and flashbacks show how Harrison Wells (Tom Cavanagh) came up with the idea for the particle accelerator.

Ralph Hemecker directed the episode written by Andrew Kreisberg (#117). The "Tricksters" episode of The Flash will air on Tuesday, March 31, 2015 at 7 PM ET on The CW.
