The Carrington family will face the unknown on all fronts. Dealing with the fallout from the startling second season finale, Fallon is surrounded by a host of rivals looking to destroy her, the most wicked of which is her own brother, Adam, who takes the idea of 'sibling rivalry' to a whole new level of crazy. At the same time, Fallon and Liam attempt to keep their romance sane, but secrets and skeletons from her closet will make that more difficult than ever. And after a year of 'me' time, Blake will jump back in the game, ruthlessly determined to reclaim what's rightfully his.
