Watch LookMovie. Filmmaker Vikram Jayanti offers this gripping documentary that follows legally blind dogsled musher Rachael Scdoris as she competes in her third Iditarod, the punishing 1,161-mile dogsled race through the treacherous Alaskan wilderness. Accompanied by helper and Iditarod veteran Joe Runyan, Scdoris calls upon a remarkable well of courage and determination to contend with the dangerous race course, unusually vocal critics and her disability.
