This earnest evangelical drama draws inspiration from the Bible verse Hebrews 4:16 ("We will find grace to help us when we need it") in its tale of a police officer named Bill "Mac" McDonald (Michael Joiner) whose life is shattered (and his faith severely challenged) when he loses his son in a tragic accident. Eighteen years of rage and hostility ensue, marked by rapidly crumbling relationships with his family members and strained relationships on the force. Events reach a fever pitch, however, when Mac gets partnered up in the squad car with Sam Wright (Michael Higgenbottom), an African-American ordained minister-turned-cop with a loving and supportive family. Despite the many obstacles standing in the way, the men gradually work toward overcoming their differences and helping one another.
