In the mid-nineties, while living in Mexico, the U.S. journalist, Leam Gaertner, and a British activist by the name of Fiona had two sons: Nico and Sebastian. Political threats prompted their relocation to Oklahoma, where they had a house in the small town of Ava. The couple's incessant activism resulted in a tragedy that ruptured the family, triggering the film's present-day events. In late 2016, Nico, now 24, is once again living in Mexico. His obsessions -and a restlessness that consumes him- are justified because Sebastian, who was left in Oklahoma with the now bitter and cynical Leam, is traveling to Mexico by road, determined to put the pieces together once and for all. Nomadic images intersect and create the story of these two brothers who are eager to find their true identity and to unveil their family's buried secrets, while they find themselves incapable of engaging into dialogue. All of this is tinted by the puzzling closeness between Mexico and the U.S.
