THE BORGIAS is a complex, unvarnished portrait of one of history's most intriguing and infamous dynastic families. Jeremy Irons returns in his role as the cunning, manipulative patriarch of the Borgia family who ascends to the highest circles of power within Renaissance-era Italy to become Pope Alexander VI. Seeking to consolidate his power, Alexander enlists his family to take an oath of revenge on the great noble houses that dared to stand against him, causing his Papacy to face political turmoil once again. But Alexander's real problems lie with his children, all of whom are growing up and defying his authority. Daughter Lucrezia forges an unlikely alliance between her mother Vanozza and her father's mistress Giulia, and together they plot to battle Vatican corruption. The sibling rivalry between sons Cesare and Juan will soon turn to hatred as their father's unwavering favoritism toward Juan triggers Cesare to engage his dark side. Elsewhere in Rome, Alexander's old enemy Della Rovere has entered the city incognito and conspires to assassinate him.
