An account of the coming about of the famous Christmas hymn, Silent Night, written by two Austrians in need on Christmas Eve. When they discover the organ has been damaged by mice, a priest presents a Christmas poem to the organist who puts it to a simple melody. The boys' choir replaces the bellows of the organ, and moves the hearts of many in the small Austrian church. The hymn travels through Austria by many hands, anonymous, until rediscovered by the organist's son.
