Dan Is Missing (2013)

Andy and Nick were best friends in college but they haven't spoken in eight years. When Andy's brother Dan goes missing in the Adirondack woods of upstate New York, he calls up Nick, who lives in the area, and the two go searching for Dan. In each of these seven vignettes, the two men experience each of the seven stages of the grieving process, both about the loss of Dan, and about the loss of their friendship.
