Luke Hansen's writing may be known to America readers, but his day job—as the volunteer coordinator at Red Cloud Indian School on the Pine Ridge Indian Reservation in South Dakota—hasn't been quite so visible. However, a new special on ABC's 20/20 hopes to shed light on the land and people of the reservation, and includes visits to the Red Cloud Indian School, where Hansen works. Titled "Hidden America: Children of the Plains," the documentary aims to highlight the struggles and triumphs of the Oglala Sioux children who live there, often in poverty. The program is scheduled to air tomorrow, Oct. 14, at 10 p.m./9 p.m. Central. We're hoping Hansen will share his thoughts on the accuracy of the completed project once it airs, so check back for updates. Watch a preview here.
