I Travel Because I Have to, I Come Back Because I Love You(2010)

Overview:

José Renato, a 35-year-old geologist, is sent out on a solitary expedition to the hinterlands of northeastern Brazil. The purpose of the trip is to assess possible routes for a canal that will connect the area with the only major river in the region. As the field trip progresses, it becomes clear that Renato shares with those places the same emptiness, sense of abandonment and isolation.
