A shell of the man he once was, estranged from his family for nearly twenty years, he has lost his faith and the will to go on. Aside from his friend and business partner, he finds the only other person he can talk to is his housekeeper, Sarah.

Sarah’s self-appointed mission is to bring Abraham back to the church and the family he left behind. What she didn’t plan on was falling in love along the way. Just when it appears a bright future lies ahead for the couple, tragedy strikes. As Sarah and Abraham are put to the ultimate test, will their faith bring them through it, or will Abraham slip away from God forever?
