Long-haul truck driver Lowell Ferguson is on the brink of suicide. He is haunted by the guilt of a horrible secret from his senior year of high school. Therapy and antidepressants aren’t able to lift him out of depression. At twenty-eight years old, he believes his life has dissolved into a meaningless annoyance. Only the strong bond with his lone friend—a Chihuahua named Rufus—keeps him from choosing death. But when Lowell learns Rufus may have cancer, he fears there will be no reason left to live if his beloved dog dies.

While awaiting the diagnosis, he comes across a flier for a Christian support group promising hope and freedom. A skeptic and an apatheist, he nonetheless reluctantly decides to join the group. Through this joining, he finds what he has been yearning for—a path toward leaving the darkness of depression. This first step provides Lowell the courage to do what he must to escape his guilt and finally confront his past.
