Move fast to avoid spoilers!
Season One (2014-2015)
The first season of The Flash focuses on Barry Allen (Grant Gustin) becoming the titular hero, and his quest to discover the secret identity of the evil Reverse Flash in order to free his father from prison.
When the particle accelerator at Star Labs explodes, Barry is hit by lightning during the resulting energy wave, knocking him into a coma for six months. Upon waking he discovers that he has developed the ability to move at superhuman speed.
Working alongside the staff at Star Labs including Cisco Ramon (Carlos Valdes), Caitlin Snow (Danielle Panabaker), and Dr Harrison Wells (Tom Cavanagh), Barry takes on the identity of The Flash in order to fight crime and stop other meta-humans who are using their abilities for evil.
Over the course of the season, Barry discovers that Dr Wells is actually the evil speedster, The Reverse Flash, who comes from the far future and is responsible for the murder of Barry’s mother fifteen years before. When The Reverse Flash tries to return to his own time, Barry stops him, resulting in his death, which tears a breach in reality.
Season Two (2015-2016)
The second season of The Flash deals with the repercussions of the first season, with the breach in reality opening a doorway to an alternate Earth, home to the monstrous speedster Zoom.
After the opening of the breach in reality Caitlin’s husband, the metahuman known as Firestorm (Robbie Amell), closes the singularity at the cost of his own life. Despite having saved Earth from destruction, this results in a number of breaches between Barry’s reality and another Earth, Earth-2.
The evil speedster Zoom begins to send metahumans through to Earth-1 in order to challenge Barry in order to weaken him so that Zoom can steal his speed for himself. Encountering evil versions of people they know, and even themselves, the team manage to defeat Zoom’s minions.
Desperate to achieve his goals, Zoom comes to Earth-1 and murders Barry’s father (played by original TV Flash, John Wesley Shipp), who has since been released from prison. Having to break the rules of time travel to defeat Zoom, Barry works with another version of himself to beat the villain, resulting in Zoom being dragged into the Speedforce to become the zombie like Black Flash.
After losing his father to Zoom, Barry decides to travel back in time to stop the loss of his parents, going back to the night his mother was killed and stopping The Reverse Flash, changing the timeline forever.
Season Three (2016-2017)
Season Three of The Flash sees Barry having to live with the consequences of changing the timeline and having to fight against the speedster Savitar (Tobin Bell) in order to save the woman he loves.
Living in a new timeline where his parents are alive and he’s no longer The Flash, Barry soon learns that things aren’t better in this new world, known as Flashpoint, and tries to put reality back into place.
Barry succeeds in undoing the events of Flashpoint, but doesn’t get things completely back to normal, resulting in the death of Cisco’s brother, Caitlin developing powers, and the appearance of the villain Dr Alchemy.
After learning that Dr Alchemy is in fact working for Savitar, who claims to be the god of speed, Barry finds himself outmatched and has to work alongside his new partner Kid Flash in order to stop him.
When Barry accidentally slips into the future he sees Savitar murder his fiancee Iris (Candice Patton), and makes it his mission to change these events. Succumbing to her new powers, Caitlin become the villain Killer Frost and works with Savitar to defeat The Flash.
Discovering that Savitar is in fact an evil version of Barry from the future, the team manage to change events and are able to save Iris, though at the loss of one of their own; H.R. Wells, who gives his life for the cause.
Getting Caitlin back to her true self, and along with the help from speedster allies from other world, they are able to defeat Savitar once and for all. Due to his manipulations of the timeline and his misuse of the speedforce, however, Barry is drawn into the speedforce, apparently lost forever.
The Flash is scheduled to return on Tuesday 17th October in the UK on Sky. Let us know if you’ll be watching the new season!
