Hello Blurt,
We start by seeing the JLA battling through several Crises situations when Wondie tells that league will be dealing multiple crises at once and tells that the history ofvJLA's crises is a history of their triumphs.
We cut to several dark knights ( Warbat, Grim knight, Mindhunter.) Scanning for any threats.
We then see Jarro, Bats, Wondie, sups, swamp thing, Harley and Hex go into the as Swampthing escorts them to the Castle Bat, where they 're informed that the Flashes are being chased by the Darkest knight.
They then encounter other dark knights, Chiroptor, Ark, The pearl, Black Monday and Kull. Kull reveals to Wondie that she is hers and Batman's daughter.
Jarro psychically opens a way out of the predicament, and Wondie uses the Alfred box vibrations to sense the portal must near.
Sups then senses the a god like beast is near them, Batman uses a Bat-flare and reveals they are in the chamber that's holding the demon Barbatos.
When then get a fight between Harley, hex and the Robin king, where Robin king shoots and kills Jonah hex.
Wondie, Sups and Bats the ride the portal, Bats gets attacked by cannibal creatures and meets the Anti-monitor, Sups Meets the Final crisis Darkseid and Wondie I the infinite crisis meet Superboy Prime.
Thanks
