From Old Time Movies and Radio:

“Mary Henry is enjoying the day by riding around in a car with two friends. When challenged to a drag, the women accept, but are forced off of a bridge. It appears that all are drowned, until Mary, quite some time later, amazingly emerges from the river. After recovering, Mary accepts a job in a new town as a church organist, only to be dogged by a mysterious phantom figure that seems to reside in an old run-down pavilion. It is here that Mary must confront the personal demons of her spiritual insouciance.”
