After being struck by lightning, CSI investigator Barry Allen awakens from a nine-month coma to discover he has been granted the gift of super speed. Teaming up with S.T.A.R. Labs, Barry takes on the persona of The Flash, the Fastest Man Alive, to protect his city.

Barry discovers his powers and puts them to the test, only when he finds its no longer a test but the real thing when he encounters a certain someone.

Barry changes into the Flash when six gunmen storm a university event honoring a scientist, but his heroics don't match up to his expectations. Meanwhile, Iris becomes even more intrigued by the "red streak."

Barry and the team go after the Mist, who possesses toxic gas powers, and they reflect on the night Caitlin's fiancé died. Meanwhile, Henry gets a long-awaited visit from Joe, and Iris and Eddie continue to keep their romance a secret from Joe.

The Flash battles Captain Cold after the villain is involved in a robbery and plots to steal the Kahndaq Dynasty Diamond.

After a bomb explodes downtown, the army rolls in and takes over. When Joe learns Iris is writing about 'The Streak' and tries unsuccessfully to have the story stopped, Barry decides to have The Flash pay her a visit.

The Flash faces a new meta-human named Tony, who can turn himself into girded steel at will.

The Flash goes up against Farooq aka Blackout, a metahuman who can harness electricity.

Barry is thrilled when Oliver, Felicity and Diggle come to Central City to investigate a case involving a deadly boomerang. The crossover continues on Arrow S03E08 The Brave and the Bold.

Barry enjoys the annual tradition of tree trimming and gift exchange with Joe and Iris. He gives Iris a touching gift, but the moment is interrupted by Eddie’s arrival.

While Barry strives to become fast enough to defeat Reverse-Flash, Captain Cold returns to Central City with a partner and takes Caitlin hostage to force a confrontation with the Flash.
