The official synopsis for the film is as follows:
After the events of Captain America: Civil War, King T’Challa returns home to the reclusive, technologically advanced African nation of Wakanda to serve as his country’s new leader. However, T’Challa soon finds that he is challenged for the throne from factions within his own country. When two foes conspire to destroy Wakanda, the hero known as Black Panther must team up with C.I.A. agent Everett K. Ross and members of the Dora Milaje, Wakanadan special forces, to prevent Wakanda from being dragged into a world war.
The trailer pretty shows us what we’ve already seen before in previous trailers, extending some of them with extra dialogue. Black Panther stars Chadwick Boseman, Michael B. Jordan, Lupita Nyong’o, Danai Gurira, Winston Duke, Forest Whitaker, Daniel Kaluuya, Florence Kasumba, Angela Bassett and Sterling K. Brown.
Black Panther is scheduled for cinematic release on the 16th February 2018.
