Locked in Silence (1999)

A story of a young boy who becomes an elective mute after witnessing what he believes to be the killing by his older brother of a teenage boy. The young boy's brother then tells him not to say anything because of the trouble it would cause in the family... so he doesn't say anything again. The problem is that the young boy so enjoys his acceptance by others of his mutism that it brings his family, a loving and caring farm family, to the brink of financial ruin in medical and psychological costs to cure him. Based on a true story, this is the intelligent telling of a family in crisis, and the work of doctors in dealing with this mental illness.
