Season 4 (The Flash: 2014)

“	My name is Barry Allen, and I am the fastest man alive. To the outside world, I am an ordinary forensic scientist. But secretly, with the help of my friends at S.T.A.R. Labs, I fight crime and find other metahumans like me. But I became lost in time. It took everything in my friends' power to bring me back. And in doing so, our world was opened up to new threats, and I'm the only one fast enough to stop them. I am The Flash.	”

The fourth season of The Flash premiered on October 10, 2017, and concluded on May 22, 2018. The season consists of 23 episodes.

Synopsis

Running up against an evil time remnant version of yourself is something no one should ever have to do, but that's exactly what faced Barry Allen (aka The Flash) as he fought to save the life of fiancée Iris West from the God of Speed known as Savitar.

Barry's victory was short-lived, however, as an unbalanced Speed Force began to wreak havoc on Central City, forcing Barry to sacrifice himself for the greater good.

With The Fastest Man Alive now trapped inside an extra-dimensional energy, and unknown dangers lurking in the shadows, it will be up to Team Flash to free Barry from his own personal Hell.^[1]
