Who decides what is right? How do we judge our actions? And how do we live with ourselves when things go wrong? Following his father's death, troubled idealist Nick abandons his safe London life for a remote desert village in Africa, lending his engineering skills to build a children's hospital. Adrift from the world he knows, dangerous currents soon pull him in: a simmering family conflict, hidden corruption and violence, a killing drought, attraction to his host's lonely wife. But when he realizes a water well could offer a way out for the village and redeem his guilty conscience, he takes matters into his own hands. It's a decision that changes everything - for him, and for everyone he loves.
