Lifetime’s Casteel family movie series event comes to a close Saturday night with the premiere of “Web of Dreams,” the film adaptation of the final book in V.C. Andrews’ popular book series.

While the other films were all sequels, “Web of Dreams,” which was directed by Mike Rohl (“When Calls the Heart,” “Summer of Dreams”), is actually a prequel movie that finally explains the history of the unique family.

“Heaven’s mother Leigh (Jennifer LaPorte) had to escape from Farthinggale Manor and the secrets she harbored. Falling into the arms of Luke Casteel Sr. (Tim Donadt), his devotion promised her hope as only Luke knew her deepest of secrets,” the synopsis shares. “Bravely she bore the suspicions of the hill folk, as she tried to grasp the happiness that long eluded her. With a baby girl, Heaven, on the way, she hoped for a chance at happy ever after.”
