All Sarah and Evan Davis ever wanted was a child, but after two dangerous miscarriages, they face an unbearable and uncertain future. Evan tries to console her, but Sarah refuses to be swayed. Against doctor's advice, Sarah allows herself to get pregnant, and this time gives birth to a beautiful boy, Kade. At long last, both Sarah and Evan believe their lives are complete, at least until their son is diagnosed with autism, something neither of them expected: a change that leads to an even harsher reality: sometimes love, no matter how hard, must be enough.
