Samuel anoints David, and David plays for Saul. The Philistines under King Achish gather in the Valley of Elah, where Goliath challenges Israel. David brings supplies to his brothers, and Saul fits him with armor that is too large. David kills Goliath with a sling and a stone, and the inspired Israelites defeat the Philistines.
Saul then realizes David is the prophesied king and feels betrayed. He throws a spear at David and frames him for attempted murder. David flees. Jonathan's arrow topples a statue of Saul and covers the escape. Saul's army kills those who help David, and David's family leaves Bethlehem. David collapses in the wilderness, is revived and takes shelter in a cave, where he is reunited with his family.
David insists he remains loyal to Saul. When Saul enters the cave to drink, David spares him and cuts only a corner of his robe. He reveals himself, and Saul forgives him and leaves. David's family returns to Israel. The Philistines come back, and David and Eliab infiltrate the Philistine ranks to help Saul. On the battlefield they learn the Amalekites are involved. The research did not cover the final scenes in detail. The film's ending leaves David's kingship largely ahead of him, and it presents Israel's survival and David's integrity as proof that the crown belongs to God.
