After trying everything to win back all the books from the evil clutches of Tobor, Sema is about to pack away her super costume and give up being Super Sema. A desperate visit to The Great Tree conjures up the spirit of her mother (voiced by Lupita Nyong’o), who rekindles her sense of self-belief. Sema realizes giving up is not an option. Super Sema is back, and this time she means it!
