Synopsis

The movie picks up after the anime series' Final Exam, where now the U.A. Class members are going on a field trip during the summer break. Before they head off for it, however, All Might and Deku get invited to go to a floating and mobile manmade city called "I Island". There is currently a special "I Expo" convention being held there, where researchers gather to research quirks as well as hero supplemental items. While the two are there, suddenly a villain hacks into the city and takes the people living there hostage. It is now up to the Hero Association to save the city.
