At the young age of 14, orphaned Catherine marries into the 16th-century French court. But after realizing her husband is in love with another woman, her future is suddenly uncertain.

Catherine must find those who she can trust - both within her personal entourage of courtiers and members of the royal court - while outmaneuvering anyone who underestimates her determination to survive at any cost.

See how Catherine de Medici defied all odds to become one of the most powerful and longest-serving rulers in French history.

Based on the book 'Catherine de Medici: Renaissance Queen of France' by Leonie Frieda.
