Struggling to find his place in the world while juggling school and family, Brooklyn teenager Miles Morales is unexpectedly bitten by a radioactive spider and develops unfathomable powers just like the one and only Spider-Man. While wrestling with the implications of his new abilities, Miles discovers a super collider created by the madman Wilson "Kingpin" Fisk, causing others from across the Spider-Verse to be inadvertently transported to his dimension.

After reuniting with Gwen Stacy, Brooklyn’s full-time, friendly neighborhood Spider-Man is catapulted across the Multiverse, where he encounters the Spider Society, a team of Spider-People charged with protecting the Multiverse’s very existence. But when the heroes clash on how to handle a new threat, Miles finds himself pitted against the other Spiders and must set out on his own to save those he loves most.

Miles Morales is now a fugitive on the run from every other Spider in the multiverse, and Gwen and his other friends might not be enough to help him.
