The plot of "Beyond the Spider-Verse" will pick up directly from the cliffhanger of "Across the Spider-Verse". Miles has turned the Spider-Society, centered around their leader Miguel, against him. They believe that the likely impending death of Miles' father should not be prevented. It is deemed an inevitable fate – one that Miles cannot accept.
However, during his escape from the Spider-Society, our protagonist ends up on the wrong Earth. There, he encounters an alternate version of himself, who has become the villain Prowler in this reality. Miles is now held captive by the antagonist. Meanwhile, Gwen assembles a team including Peter B. Parker and other friends to help Miles.
A central theme in "Beyond the Spider-Verse" will also be the threat posed by Spot, who already played an important role in the second movie. Spot is a former scientist who gained special powers as a result of an explosion at the end of "Into the Spider-Verse". He has become a being covered in black spots – which he can use for teleportation. Spot can travel through spaces and even dimensions via these portals. However, he is anything but happy with his condition: he blames Miles for it and therefore wants to kill his father. At the same time, because of his abilities, he poses a threat to the entire multiverse.
Miles will also have to confront the darker version of himself in "Beyond the Spider-Verse".
