Graphic, sometimes chilling depiction of the story of a rookie FBI agent teaming up with a local game tracker and the tribal police chief to solve the murder of an 18-year-old native American girl who froze to death in the wilds of Wind River Indian Reservation in remote Wyoming wilderness. What formal roles exist? What informal roles emerge? Are there any disruptive roles that impede the investigation? How do roles influence the investigation? How does the newcomer (rookie FBI agent) adapt to the group? How do others adapt to the newcomer?
