Lyle Hovde lives a mostly content life in rural Wisconsin with his wife, Peg, daughter, Shiloh, and six-year old grandson, Isaac. After a troubled adolescence, Shiloh has become deeply involved with an extremist church, and the devout pastor courting her is convinced Isaac has the spiritual ability to heal the sick. When the church's radical belief system threatens Isaac's safety, Lyle is forced to make a decision from which the family may not recover. -- adapted from jacket.
