Miracle Child (1993)

A despairing young widow who abandons her baby pondside among bulrushes and a man who's fighting to reclaim his own son are drawn together. A baby plops out of a rainy, stormy sky into the arms of the town's beloved, vaguely-addled spinster. Miracles suddenly reverse the town's fortunes as drought and unemployment disappear, only to be replaced by boosterism and greed.
