The Flash Season 3: Time Strikes Back Trailer Released

See what happens...when time strikes back.

A brand new trailer for season 3 of The Flash has been released and asks a very important question that will be central to the overarching storyline of the entire season - Flashpoint.

In short, Barry Allen broke the rules last season when he travelled back in time in order to save his mother from being murdered and his dad from being sent to jail. Now he has both parents, but he also created an entirely new alternate reality where everything has changed, and most importantly no one knows who he is.

Check out The Flash season 3 trailer below:

In The Flash season 3 trailer, Barry (who's looking extraordinarily confused) enters an unknown coffee shop with his dad and asks what year it is. We also get a quick glimpse of what we can assume is the major big bad of the upcoming season, Dr. Alchemy.

We also catch Barry Allen attempting to explain how he went back in time and created an entirely new existence to a mega-wealthy tech-genius version of Cisco, who doesn't even remember him in the first place.

A glimmer of hope appears when the love of his life and best friend Iris West seems to remember him when she asks, "We're something else to each other, aren't we?" It seems like Iris may be the one to help Barry fix what he broke, and it's possible that Cisco also helps on the tech-side of things.

The Flash season 3 premiers on October 4 on The CW.
