After the changes that took place in Flashpoint, Superman finds himself on the gladiator planet known as Warworld and ruled by the tyrant Mongul. He will need the help of Green Lantern Killowog (his ring was taken and locked away by Mongul) to create a rebellion and defeat Mongul without his powers, as the planet has a red sun. Meanwhile, on Earth, Batman receives a visit from Clark and Lois Lane's daughter from the future known as Lara and she warns him that if Superman dies in Warworld, in the future they will lose the war against Darkseid for not having Superman. Batman deduces that this is all happening because of Flashpoint, as in the original timeline according to Flash, Superman was on Earth. To prevent Superman's death, Batman sends Lara, Hawkman to rescue Clark.
At the end of the movie, Clark will return to Earth alone, as Hawkman will have to solve problems on his planet and Lara will return to her time.
In the post-credits scene, after defeating Mongul and heading back to Earth, Clark's ship is attacked and he is captured by Brainiac, kicking off Justice League 2, one of the five League movies I plan to create.
