I think I like the abbreviated format I used for the last two Rurouni Kenshin movies. I shall apply it again here.
The Story (based very loosely off a little-known Marvel comic of the same name):
Hiro Hamada (and I’m struggling to not write “Hamada Hiro” instead of “Hiro Hamada”…) is a teenage robotics genius who lives with his elder brother, Tadashi, under the care of their aunt. Hiro gains entry to the same university as Tadashi when he presents his latest invention – microbots – at the university’s exhibition. Tragically, Tadashi is killed in an accident on the same day. But Tadashi leaves behind his invention – a robotic healthcare assistant named Baymax. Hiro accidentally activates Baymax one day but doesn’t think much of it until Baymax (following and Hiro’s last remaining microbot) leads him to discover that a mysterious masked man is making more microbots just like his. Hiro forms a team with Tadashi’s university friends – Wasabi, Honey Lemon, Gogo and Fred – to track down the masked man, whom he suspects of having started the fire that killed Tadashi.
