No longer able or willing to leave her home, 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 residents of quirky Bright's Pond, Pennsylvania, plan to erect a sign on the interstate in her honor, but Agnes wants no part of it. Then a stranger comes to call asking for his miracle, and the town is turned on its head.
