This Halloween Greybeard returns to extract his own form of revenge.

It has been six long years since Santiago Ramos, a retired U.S. Deputy Marshal, lost his best friend, Jimmy Douglas Greyson. Now, every Halloween, Santiago waits at his ranch in Phoenix, Arizona, for the arrival of his friend— Jimmy, and his father, the legendary ghost known as Greybeard. This year everyone gets more than they bargained for when Greybeard and Jimmy return to rescue Santiago's grandson, Ramey, who has been kidnapped along with three other children from a Halloween party. Greybeard sets out on a mission to find the missing children, proving that love and vengeance can drive a ghost to extraordinary lengths.

What would Greybeard do to save someone he loves? The answer is whatever is necessary.
