Spitfire (1934)

Mountain girl Trigger Hicks, a fierce loner equally handy with a rock or a prayer, is in danger of having her faith-healing mistaken for witchcraft by the neighbors. She shows a vulnerable side when John Stafford, a philandering engineer working on a new dam, is attracted to her. Matters come to a head when Trigger "rescues" an abused baby from its parents, and seeks help from the engineers.
