Mark Kendall documents the life of a U.S. school bus after it’s decommissioned, following it to Mexico, where it’s auctioned off; to Guatemala City, where it’s used for public transit; and finally to the U.S.-Mexican border, where it transports aspiring migrants on behalf of a small private business. The bus itself narrates the opening passages, establishing a storybook tone that Kendall maintains throughout the movie. This sense of childlike wonder, and the respect accorded everyone involved in prolonging the bus’s usefulness, are all the more impressive given that Kendall concludes with a sobering assessment of widespread civilian violence in Central America. In Spanish with subtitles.
