No longer able or willing to leave her home, the unusual Agnes Sparrow has committed herself to a life of prayer - prayer that has resulted in numerous miracles, both large and garden variety, including a prize-winning pumpkin.
The rural residents of Bright's Pond, a quirky Pennsylvania town, are so enamored with Agnes they plan to erect a sign in her honor on the interstate. Agnes wants no part of it and sends her sister to fight city hall. Their petitions are shot down and the sign plans press forward.
But when a stranger comes to call asking for his miracle, Bright's Pond is turned on its head and Agnes' feet of clay are exposed, forcing the town to its knees.
