The Mechanics of Borders.

Mathieu works in a cattle slaughterhouse in the region. For the past year, he has been slow to free himself from his foster family and find his own roots. When his sister Heidi, whom he has not seen for 3 years, asks him to pick her up in the depths of the United States, he renews the hope of bringing her back to his side. Despite the warning from his former foster mother, Mathieu leaves everything undone to answer his sister's call.
