Joshua Landsverk wants to repair his broken relationship with Astrid, but he is opposed to her present work and refuses to tell her why. When he encounters unexpected adversity, a surprising act of kindness brings healing to the grievous wrong inflicted years ago. Will it be enough to bring Joshua and Astrid together again?
