"Big Hero 6" is a heartfelt comedy adventure about robotics prodigy Hiro Hamada, who learns to harness his genius-thanks to his brilliant brother Tadashi and their like-minded friends: adrenaline junkie Go Go Tamago, clean freak Wasabi No-Ginger, chemistry whiz Honey Lemon and fanboy Fred. When a devastating turn of events catapults them into the midst of a dangerous plot unfolding in the streets of San Fransokyo, Hiro turns to his closest companion-a cutting-edge robot named Baymax-and transforms the group into a band of high-tech heroes determined to solve the mystery.
