Tahnaanooku’ is a visually captivating and soulful work of art. It tells a powerful story of Indigenous history, identity, and connection with the Missouri River, the earth, fire, and animals. Through surreal-like visuals and compelling music, the film weaves together past, present, and future, highlighting the impact of government control, like the Garrison Dam, on the Mandan, Hidatsa, and Arikara people. At its core, it offers a deep reflection on Indigenous identity, with Darline Deegan—activist, mother, and grandmother — sharing her wisdom and care for future generations. It serves as a poignant reminder of the importance of reconciliation with Indigenous peoples today.
