Every day, dozens of yellow American school buses leave the United States on a southward migration to Guatemala, where they are resurrected as the brightly colored camionetas that take Guatemalans to work each day. Since 2006, nearly 1,000 camioneta drivers have been murdered for not paying the extortion money demanded by local gangs. Using an observational approach, the filmmakers of this vivid new documentary chronicle the experiences of those involved with a harrowing situation.
