Battle In Heaven - Carlos Reygadas

A working-class man named Marcos and his wife kidnap a baby for ransom money, but it goes tragically wrong when the infant dies. In another world is Ana, the daughter of the general for whom he drives, who does sexual acts to any man for pleasure. Marcos confesses his guilt to her in his troubled search for relief, and then finds himself on his knees amid the multitude of believers moving slowly toward the Basilica in honor of the Lady of Guadalupe.
