Japan, 1587. Sen must find a husband to marry into her family's swordsmith business. She seeks a Christian husband, though Christianity is banned. Enter Nobuhiro. Third son of a high-level samurai, Nobuhiro fled his harsh father and apprenticed himself to a swordsmith. He yearns to prove his worth. They seem an ideal match. But for Sen, the choice is faith or family. For Nobuhiro, choosing a Christian ends any reconciliation with his family. Can love be forged from the impossible?
