Forced to preserve her kind, Caitlyn ventures to the outside world to steal human children for the demon, Lexor. She starts working at Bayside Child Care Center under the alias "Katie Whitesmith", and secretly switches the babies with elven ones. Paige, who is also working there, notices the strange occurrences, especially when her newly-born nephew, Wyatt, turns out to have been swapped for an elf.
