Caleb Knight is an ordinary boy, but with one difference... he was born with the power of the Archangel, the most powerful angel in Heaven. This power lies dormant inside Caleb until his 12th birthday, when he accepts the gift of the Holy Spirit. Once the power is awakened, Satan sends his demons to kill Caleb. Caleb's father sacrifices himself to protect Caleb, who is rescued and trained by the Angel of the Lord. Eighteen years later, Jim Sinclaire loses his wife to a violent crime and also loses his faith in God. In his moment of weakness, Jim makes a deal with the devil, which could cost him and everyone on Earth their souls. Now a full-fledged Angel Knight, will Caleb have enough power to prevent what could possibly be Hell on Earth?
