King T'Challa returns home from America to the reclusive, technologically superior African country of Wakanda to serve as his u . S .'s new chief. However, T'Challa quickly finds that he's challenged for the throne via factions within his own country as well as without. Using powers reserved to Wakandan kings, T'Challa assumes the Black Panther mantel to sign up for with girlfriend Nakia, the queen-mom, his princess-youngster sister, individuals of the Dora Milaje (the Wakandan 'unique forces') and an American undercover agent, to prevent Wakanda from being dragged into a world struggle.
