In Battle in Heaven (AKA Batalla en el Cielo), director Carlos Reygadas' searing look at the inherent hypocrisies of Mexico's social structure, Marcos Hernandez is Marcos, an overweight, poverty-stricken chauffeur who longs for a better life for his wife and young son. Desperate, the couple kidnaps an infant child for ransom. When the baby dies in their custody, this simple crime that Marcos hoped would brighten his family's future instead adds a crushing burden to his conscience and will bring dire consequences for Marcos and his wife if discovered. Meanwhile, Ana, an affluent general's daughter whom Marcos chauffeurs from place to place, secretly battles ennui by prostituting herself in a local brothel with her friends. The two confide their darkest secrets in one another, and as Marcos urges Ana to drop out of whoring, Ana tries to convince Marcos to turn himself in. Marcos, however, will not listen, insisting that true forgiveness and redemption must come from above. Batalla en el Cielo marked the second major international release for director Reygadas, after the acclaimed Japon (2002).
