On the night of February 27, 1973, a caravan of cars carrying 200 armed Oglala Lakota-led by American Indian Movement (AIM) activists-entered Wounded Knee on the Pine Ridge Reservation and quickly occupied buildings, cut off access, and took up defensive positions. When federal agents arrived, they declared, "The Indians are in charge of the town," and a 71-day standoff ensued. Compiling an astonishing amount of archival film footage (notable for the key moments it captures) and firsthand accounts from participants, Stanley Nelson creates an immersive, comprehensive account of the occupation and its fascinating complexity. The Oglala Lakota sought redress of old grievances and broken treaties (just miles from the massacre of 1890) but also demanded the ouster of Pine Ridge tribal leader Dick Wilson, who governed through corruption and intimidation as he pursued deeply divisive policies of assimilation.
