Despite recent news, there is no official synopsis on the ‘Flash’ movie. According to DC Movies Wiki, the movie is based on the Flashpoint storyline that gave birth to the New 52.

Namely, Barry Allen goes back in time in order to save his mother from death. However, his actions create a DC multiverse with an alternate catastrophic timeline.

Perhaps, to confirm the new direction is the Las Vegas Licensing Expo 2022. At the Expo, Flash’s and Supergirl’s costumes from the movie were exposed.

According to Den of Geek, Flash’s costume design is inspired from the New 52. On the other hand, Supergirl‘s costume is uniquely inspired from Injustice.
