Black Panther (film) [SEP] Plot
N'Jobu's partner reveals he is Zuri, another undercover Wakandan, and confirms T'Chaka's suspicions. In the present day, following T'Chaka's death, his son T'Challa returns to Wakanda to assume the throne. He and Okoye, the leader of the Dora Milaje regiment, extract T'Challa's ex-lover Nakia from an undercover assignment so she can attend his coronation ceremony with his mother Ramonda and younger sister Shuri. At the ceremony, the Jabari Tribe's leader M'Baku challenges T'Challa for the crown in ritual combat. T'Challa defeats M'Baku and persuades him to yield rather than die. When Klaue and his accomplice Erik Stevens steal a Wakandan artifact from a London museum, T'Challa's friend and Okoye's lover W'Kabi urges him to bring Klaue back alive.
