Mike Davidson left Texas for the mountains and ended up staying at Big Bend, where he became the man who rows visitors across the Rio Grande to the Mexican village of Boquillas. The film follows him at the crossing, an unofficial gap in the border wall system where a small rowboat still does the work that fences and checkpoints elsewhere have taken over. Davidson talks about how an outdoorsman with no plan to stay wound up running an informal ferry service, and about the odd position it puts him in: a private citizen operating a de facto international crossing point on his own initiative. Interviews and footage of the river, the boat, and the walk into Boquillas ground the story in a specific place rather than an abstract debate about immigration policy. It is a small, personal portrait of one man's routine at a spot where geography, tourism, and border politics all meet on the same stretch of water.
