A decade after Cathy, Christopher and Carrie escaped from their grandparents' attic at Foxworth Hall, "Petals on the Wind" continues to follow the twisted plight of the family as they attempt to put their sordid past behind them, but soon discover certain secrets can't be left behind. When Cathy finds herself in an abusive relationship with a fellow dancer, Julian, Christopher and Cathy are forced to face the forbidden feelings they developed for one another while coming of age during captivity. But when tragedy strikes the Dollangangers once again, Cathy returns to Foxworth Hall to confront her grandmother and seek revenge on her mother with a plan to seduce her husband Bart. When Christopher runs to Cathy's side, the two are determined to start over again - together.

The saga of the tormented Dollangangers comes to an end in "Seeds of Yesterday", in which the family continues to coexist miserably. The film follows Cathy's two adult sons, Bart and Jory, half-brothers with little in common whose lives are fueled by deeply troubled relationships, dark secrets and misfortune that come to a head in a way that will haunt the family and its progeny forever.
