The Flash Full Episode Guide

  • With 24 hours left to save Iris, Barry recruits Len Snart from the past to steal a Dominator power cell from ARGUS. Meanwhile, Joe and Kid Flash take Iris somewhere that Savitar can't find her, and Killer Frost calls Vibe out to kill him... and the last vestiges of her old self.

  • Barry takes drastic measures to stop Savitar. Meanwhile, H.R. continues to push Tracy Brand to design the trap for Savitar; and Killer Frost returns with an interesting proposal.

  • Barry and the team meet Tracy Brand (guest star ANNE DUDEK), a scientist, who may be the key to stopping Savitar. Unfortunately, Ki ller Frost is also after Tracy so Team Flash must battle their old friend, which proves to be particularly difficult for Cisco. Joe (Jesse L. Martin) and Cecile's (guest star DANIELLE NICOLET) relationship takes a big turn.

  • Barry travels to the future to find out Savitar's still-unknown identity in the hopes of saving Iris. Upon his arrival in 2024, Barry encounters future versions of his Team Flash friends, who, following the death of Iris, have become very different people, profoundly impacted by their showdown with Savitar. It will be up to Barry to infuse a sense of hope back into the team, as he proves to be hero his future friends have been waiting for. Meanwhile, back in 2017, the hunt for Killer Frost continues. Series star Tom Cavanagh directs.

  • The Flash battles Abra Kadabra (guest star DAVID DASTMALCHIAN), a villain from Earth-19, who makes him a tempting offer - release him and Abra Kadara will reveal Savitar's true identity. Desperate to save Iris, Barry considers taking the deal but Gypsy breaches in to capture the villain for her own reasons and during the melee, Abra Kadabra manages to escape. Barry is furious that Gypsy interfered but she refuses to back down, forcing Cisco to take sides. Meanwhile, Julian is still a bit cold towards Caitlin, but when she is severely injured in a battle with Gypsy, he rushes to her side.

Unable to wake her up, they turn to Team Flash to save her. However, the Music Meister surprises The Flash and puts him in a similar coma, one that Team Flash can't cure. Kara and Barry wake up without their powers in an alternate reality where life is like a musical and the only way to escape is by following the script, complete with singing and dancing, to the end.

Trying to find a way to stop them before they destroy Central City, The Flash and team are joined by Gypsy, who returns to help in the fight. Meanwhile, Jesse Quick decides she wants to stay with Wally on Earth-1.

  • When Jesse Quick informs the team that her father (TOM CAVANAGH) has been abducted, Barry, Caitlin, Cisco and Julian voyage to Earth-2 on a rescue mission to save Harry from Gorilla City. As they trek through the forest, Barry and the team are immediately captured and brought to Grodd (voiced by DAVID SOBOLOV). Grodd tells them he needs their help to stop Solovar (voiced by KEITH DAVID), the leader of Gorilla City, as Solovar wants to invade Earth-1. Meanwhile, back on Earth-1, Jesse and Kid Flash hit the streets to stop a metahuman that can control gravity, with H.R. and Joe guiding them from S.T.A.R. Labs.

  • Barry is tormented by his vision of the future where Iris is murdered by Savitar. When a criminal named Plunder (guest star STEPHEN HUSZAR) shows up in Central City, Barry recalls the villain's presence in his vision of the future and fears that if he catches Plunder, it will cement Iris's fate. Confused about Barry's hesitation to stop Plunder, Wally decides to stop in as Kid Flash. Meanwhile, Caitlin offers Julian a job.
