Despite the dangers of practicing her faith in the staunchly Protestant England, pretty Queen Henrietta Maria refuses to cast aside her Catholicism, so she finds little favour among the people. She is impetuous and loving, fond of fashionable clothes and gossip, and Charles, a family man of principle and integrity, is entirely devoted to her.
But their happy if controversial marriage is soon under threat when Henrietta is renounced as a puppet of Rome and charged with leading Protestant England back to Rome.
Soon her enemies swarm and the spies in her household prove too much. Only her loyalty and love for Charles can hope to keep him from the road to regicide.
