After years of being Kid Danger, Henry Hart thought his days of being in the Kid Danger uniform were behind him. But, when a glitch in a powerful machine sends him spiralling into a fanfiction multiverse - and an enemy from his new life follows - Henry finds himself trapped in worlds that were never meant to be real.
Meanwhile, in a small town outside of Swellview, twelve-year-old Missy Martin is trying to be something Newtown never let her be: a hero. No powers, no gadgets - just determination, a homemade costume, and a really bad habit of rushing in without a plan.
As their worlds collide, Henry and Missy must team up to fix the mess, face the past, and stop something bigger that neither of them saw coming.
Or: The Henry Danger movie we deserved.
