Isaiah Price is living the American dream. He is employed at a local Christian college where he teaches Bible and tries to mentor his students in the ways of God. Isaiah is also deeply in love with his wife, Allison, and hopes that his life will never change, until an ancient artifact is stolen from the British Museum and his life is changed forever. His father-in-law, Dr. Job McPherson, one of the seminary professors at the college where Isaiah teaches, then instructs him and his wife to get the truth out about what the relic truly is. An old pamphlet reveals that the artifact is thought to be David's Sling from the Old Testament and it is believed that when it fell into the hands of the British during World War II, it caused the demise of Hitler's Third Reich. Dr. McPherson believes that a modern-day Nazi cult has stolen the weapon and will try to use it to bring about another Nazi regime based out of Germany. Isaiah, Allison, their friends Billy and Jamelle Gardner, and two students from the college Kim-Loo Chaing and Esther Hemingway agree to set off to England and reveal that David was able to defeat Goliath because of God and not by the sling itself.

Matters get even more complicated when Isaiah and his team discover a horrifying fact that it appears that Hamas and a rogue instructor from MI6 have obtained the sling before the Nazis have. Believing that Hamas is going to try to use the sling in a terror attack against Israel by trying to hearken back to false historical roots, Isaiah and his companions rush to Israel to warn the Israeli Defense Forces before an all-out war erupts.

Throughout their mission, Isaiah and his associates learn the importance of following the will of God and the importance of friendship.
