Synopsis
Barry Allen was 11 years old when his mother was killed in a bizarre, terrifying incident and his father was falsely convicted of murder. With his life changed forever by the tragedy, Barry was taken in and raised by Detective Joe West, the father of Barry’s best friend, Iris. Now, Barry has become a brilliant, driven, and endearing CSI assistant, whose determination to uncover the truth about his mother’s strange death leads him to follow up on every unexplained urban legend and scientific advancement that comes along. Barry's latest obsession is a cutting edge particle accelerator, created by visionary physicist Harrison Wells and his S.T.A.R. Labs team, who claim that this invention will bring about unimaginable advancements in power and medicine. However, something goes horribly wrong during the public unveiling, and when the devastating explosion causes a freak storm, many lives are lost and Barry is struck by lightning. After nine months in a coma, Barry awakens to find his life has changed once again - the accident has given him the power of super speed, granting him the ability to move through Central City like an unseen guardian angel. Though initially excited by his newfound powers, Barry is shocked to discover he is not the only "meta-human" who was created in the wake of the accelerator explosion - and not everyone is using their new powers for good. In the months since the accident, the city has seen a sharp increase in missing people, unexplained deaths, and other strange phenomena. Barry now has a renewed purpose - using his gift of speed to protect the innocent, while never giving up on his quest to solve his mother’s murder and clear his father’s name. For now, only a few close friends and associates know that Barry is literally the fastest man alive, but it won’t be long before the world learns that Barry Allen has become The Flash.

Introduction
At the beginning of each episode, a voice of Barry Allen describes briefly the hardships that he faced in the past. Barry states that he will use his new powers to fight crime and find the one who killed his mother to bring justice for his father in season one. In season two, Barry states how he must now use his powers to stop the new threats that he accidentally brought into the world after finding his mother's murderer. Season three featured two different intros. The first half sees Barry facing the ultimate consequence from he went back in time to save his mother, which in turn created a new timeline, leaving him facing threats from that timeline who are manifesting powers in the 'real' world. A second version was introduced in as Barry attempts to save Iris from getting killed by Savitar right after he witnessed her future death. The fourth season mentions the new threats Barry’s friends brought after they got him out of the Speed Force.
