The Flash: Tricksters Synopsis Released Online

The CW has released the official synopsis for "Tricksters," the new episode of The Flash hitting the airwaves on March 31.

The episode sees the hugely-anticipated return of Mark Hamill, who played the villainous Trickster in the 1990 version of The Flash. Adding symmetry to that will be the fact that Henry Allen, played by 1990 Flash John Wesley Shipp, will play a key role in the episode.

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.
