(from The CW's press release, May 2016) Life changed for Mary Queen of Scots in the third season of REIGN. Her beloved husband, Francis, died, destabilizing France. Francis' brother, a boy-king, took the throne, leaving Mary with little solace and a great need for power. As her cousin, Queen Elizabeth, fought for legitimacy against an unyielding patriarchy in England, Catherine and Mary came to a painful realization: they have their battles to fight as well, and it is better if they do so alone. Season four of REIGN finds Mary rising to the challenge, taking back her country and establishing her rule in Scotland, the land of her birth but a wild nation foreign to her, and now, once again, her home. Even as our canvas expands to welcome a new court in Scotland with new players, including Mary's half-brother James, and the men who vie for her hand, the French Court grows as well. Catherine gave France many heirs - too many, as it turns out. We will meet more of her brood, who are amusingly and dangerously at each other's throats. Our queens will make wise choices and knowingly brutal sacrifices; their fates, especially Mary's and Elizabeth's, are not only intertwined but increasingly inescapable. It is a season of impossibly high stakes, unexpected betrayals, sexual exploits, a royal wedding, a royal birth and a rising body count as three queens in three nations fight for their people, their loves, and their lives. REIGN is produced by CBS Television Studios and Whizbang Films/Take 5 Productions with executive producers Laurie McCarthy ("The Ghost Whisperer"), Frank Siracusa ("Beauty And The Beast"), John Weber ("Beauty And The Beast"), Patti Carr ("Beauty and the Beast," "90210") and Lara Olson ("Beauty and the Beast," "90210").
