It's 2014. Grieving the loss of family members and friends killed in a plane crash, renowned megachurch pastor Priscilla Sinclair sits on her patio, prepared to take her own life. But before she can end it all, a stranger shows up at her Virginia home and changes everything. Trying to strengthen her faith, the stranger challenges Priscilla to lean on God's promises and on the examples of faith left to her by her ancestors. He tells her a story she has never heard before. The story goes back over 3,000 years, beginning with Aaron, God's designated high priest during the Exodus, and explores the line of designated ones through the times of King David, Solomon, the exile in Babylon, the crossing of the Arabian Desert into Saba, the migration across the Red Sea into Axum, the birth of Christ, and the lives of the generations that have followed. In this thrilling journey through history, Priscilla is given a chance to go from failure to faith and live to fight another day. But will she accept the stranger's challenge?
