Catherine of Aragon arrives in England to wed Prince Arthur, heir to the English throne, in a marriage contract intended to forge an alliance between the two nations.

The English throne seems within Catherine's reach, but an unfortunate twist of fate means that her future now lies in the hands of her unstable older sister.

The fate of England hangs in the balance when the Tudor family is rocked by tragedy. Catherine risks everything to find out if Harry still loves her.

With a powerful alliance with Spain and an heir sleeping in his crib, what could go wrong for glamorous royal couple Catherine and Henry?

While meg risks all for love, a pregnant Katherine struggles with the nauseating possibility Henry is cheating on her.

When the plague hits London, the court flees to Hampton court, but Maggie and Thomas remain in an empty and surprisingly romantic palace.

As Henry loses himself to madness, the stakes have never been higher for Katherine - her husband has become a threat to her life.
