When Priscilla was 12, her father was killed in a car accident which left her a quadriplegic. Hamilton was born with only the use of his right arm. Both are children of single parents, starting at the same high school as freshmen. Through her husband, a police detective, they meet another Functional Needs adult who is host to the Archangel Raquel. From her they learn they must work with other angels and archangels seeking willing hosts in this plane of existence in order to prevent the opening of the Seven Gates of Hell on Earth. Without their sacrifice using their newfound God-given abilities, the planet will be overrun by demons, prompting Armageddon and the end of the world as we know it.
