Impoverished, childless and living in a garbage dump, Miguel and Lina become instant celebrities when Lina miraculously becomes pregnant. But Lina gives birth to a fish, which increases her celebrity but leaves Miguel humiliated and the couple at odds. What follows is an illuminating examination of how this unusual family copes and compromises in the face of a modern-day miracle.
