The West Coast debut is scheduled Thursday for the documentary film "Dakota 38," at Seattle University's Pigott Auditorium

“Dakota 38,” the rough cut, will be presented Thursday evening for its first West Coast public screening, hosted by Seattle University.

The film was inspired by Lakota spiritual leader Jim Miller, who in the spring of 2005 had a dream in which he rode 330 miles on horseback. He eventually came to a riverbank in Mankato, Minn., where he saw 38 of his own ancestors hanged. He soon discovered that he had dreamed of the actual largest mass hanging in the United States, ordered by President Lincoln in 1862.

In December 2008, Jim and others retraced the route of his dream on horseback in an effort to bring healing and reconciliation to all. “Dakota 38″ is a feature-length documentary film by Smooth Feather Productions that tells the story of the 330-mile journey.

Admission is free, but limited. For a ticket, go to Brown Paper Tickets, www.brownpapertickets.com/event/136940

The film will be shown at Pigott Auditorium, 1016 Marion St., on the Seattle University campus at 6:30 p.m. Miller and other Indian leaders will take questions afterward.

Gail Lasprogata, director of Seattle University’s Center for the Study of Justice in Society, who invited the screening to campus, said, “This is a film that should be seen everywhere, it is a gift.

“There is a real need for this healing message.”
