Frank has farmed all of his life.  Frank took care of his Mother and Father and the several hundred acre of corn year in and year out. 

And then a box, filled with hand written music, is purchased by Jane and her young son for $10. 

The box, the music box, as it comes to be known to all three,  holds revelations for Frank about a Father he thought he knew and a chance for Jane to help a man discover a history he didn't know he had and for a young boy to realize that yesterday never leaves today or tomorrow.
