Quemada-Díez brings a gritty realism and social conscience to a story about the excitement and horror young Central American migrants regularly face in trying to make it to the United States. Sara, a Guatemalan teenager, chops her hair off and disguises herself as a boy. She’s joined by her friends Juan and Samuel on a thrilling and brutal journey north, hopping freight trains heading for Los Angeles. As the group faces life-and-death challenges from bandits and corrupt law enforcement, they learn crucial life lessons about friendship and loyalty. This poetic thriller was inspired by the true stories unfolding daily along unnamed railroad tracks, and the remarkable cast of untrained actors won a special prize in the Un Certain Regard section of the Cannes Film Festival. “A very substantial movie, with great compassion and urgency.”—The Guardian, London.
