Spencer and Laura Peterson with their children Luke and Anna are coping with the loss of their eldest son, Caleb, to the War in Afghanistan (2001–present). They are visited by David Collins, a former army Sergeant and Caleb's best friend. He announces to the family his reason of visit; to help Caleb take care of the family. David is polite, warm and friendly toward the family, and Laura offers to let him stay as long as he needs to.
