While volunteering to help prisoners earn their high school equivalency, Charlie Kirby meets Caleb Farmer, who asks his help to write a letter to his long-lost son, Junior, to make amends. Touched by Caleb's story, Charlie agrees to help. When Charlie manages to track down Junior, he discovers the man has long since changed his name to James Marshall and wants absolutely nothing to do with his father. Charlie understands James's anger; Charlie spent most of his adolescence trying to convince his own incarcerated father to see him, but his father always pushed him away. Now, Charlie has nothing but regret for the past and the lost opportunities, and he wants to spare James the same fate.
