The anime smash hit that has swept the world now makes its debut on the big screen! Our favorite young hero-in-training is in for a wild ride when villains threaten the artificial moving city, I-Island. Deku and All Might receive an invitation to I-Expo, The World's Leading Exhibition of Quirk Abilities and Hero Item Innovations. Amid the excitement, Deku meets a girl who is Quirkless, just like he once was. Suddenly, I-Expo's Top-Of-The-Line Security System gets hacked by villains and a sinister plan is set in motion. It's a serious threat to Hero Society and one man holds the key to it all.
