Amidst financial pressures and the uncertainties of WWI, Pastor Frederick Lehman begins to write a song about the love of God. When he gets stuck on the third verse, ten-year-old Blynn comes to the rescue by calling a sibling council and laying out a strategy to help Papa write the song. Along the way they waste a lot of paper, explore an old asylum, meet a real Jewish Rabbi, and learn about events that took place more than eight centuries earlier. Faced with failure and grief, Blynn is left grappling with a desire to love God. Can Papa help Blynn discover the truth about God's love?
