The following morning, Christy finally finds a pediatrician in the hospital that is able to diagnose Anna with an abdominal obstruction, and he tells them he must operate immediately or she will die. Doctors find no signs of illness, except to say it could be either acid reflux, or lactose intolerance, but Christy is not convinced by this. On March 20, 2008, Anna wakes up her family at midnight because of an intense stomach pain, severe enough that her parents decide to take her to the hospital.
One day, Anna starts to vomit, and when is examined by her doctor, he does not find anything abnormal.
Set in Burleson, Texas, between 20, the film centers on a little girl named Anna ( Kylie Rogers), daughter of Christy Beam ( Jennifer Garner).
