Dalton proves to be a demanding taskmaster and he demands much of Allen—almost too much in Allen's eyes. Allen teeters on the brink of leaving his two-year mission almost as soon as it begins. Allen witnesses another missionary lose his faith and abandon his own mission. Allen changes his mind as he finds the sacrifices others have made to be on a mission, such as ostricization from family. His own companion, Elder Dalton, dropped out of medical school to serve a mission and is fighting a losing battle with brain cancer. After a trial of his faith and some earnest soul searching, Allen finds untapped courage and embraces his work as a messenger of God.
