"Heaven" introduces the infamous Casteel family, the least regarded of all the families living in the poverty-stricken foothills of the mountains of West Virginia. Yet the eldest daughter, Heaven Leigh Casteel (Annalise Basso), was still the smartest girl in the backwoods and determined to redeem her family name. However, her dreams become deferred the day her stepmother flees and her selfish father Luke (Chris William Martin) sells her and her four siblings to different families. Heaven is sent to live in the home of Luke's deranged ex-lover, Kitty (Julie Benz), who torments Heaven as Kitty's husband, Cal (Chris McNally) lures Heaven into a forbidden relationship while she fights to reunite her siblings.
"Dark Angel" picks up directly after Heaven (Annalise Basso) finds a new life in her estranged grandmother and grandfather, Jillian (Kelly Rutherford) and Tony Tatterton's (Jason Priestley) exquisite Boston mansion, Farthinggale Manor. But even in the world of the wealthy, there are strange forebodings, secrets best forgotten. As Heaven reaches out for love, she is slowly ensnared in a sinister web of cruel deceits.
Heaven is now happily married and ready to settle back in her hometown. But during a visit to Farthinggale Manor, Heaven is persuaded to stay. Lured by Tony Tatterton to live among the wealthy and privileged, Heaven seems to have it all until the ghosts of her past rise up again, threatening her precious new life.
Gates of Paradise quickly turns tragic when Heaven's daughter Annie finds herself orphaned and crippled. Whisked off to Farthinggale Manor by Tony Tatterton, Annie pines for her lost family, especially for her half-brother Luke. Without the warm glow of Luke's love, she is lost in the shadows of despair and forced into submission by Nurse Broadfield. When Annie discovers a cottage hidden in Farthinggale's woods, the mystery of her past deepens. Even as she yearns to see Luke again, her hopes and dreams are darkened by the sinister Casteel spell.
Leigh VanVoreen had to escape from Farthinggale Manor and the secrets she harbored. She fell into the arms of Luke Casteel, whose devotion promised her hope. Only Luke knew her deepest secret. Bravely she bore the local folks' suspicions as she grasped for the happiness that had long eluded her, awaiting the birth of her child and hoping for a chance at happily-ever-after.
