Concerned that the pending marriage of King Louis Philippe of France's son to the Spanish Queen will form a dangerous alliance, Victoria sets sail on her first voyage to the continent in an attempt to deter the wily French King.

Accompanied by royals and servants alike, Victoria quickly realises that she will need to have her wits about her if she is to make the charming - but not altogether trustworthy - Louis Philippe take her seriously as a Queen.

Turning to Albert for support, she finds him distant. Unknown to her, he's still reeling from the traumatic revelation about his parentage, and driven to despair by the debauchery and scandal of the French Court.

Left to take on Louis Philippe alone, does Victoria have what it takes as an international leader to finally outsmart him? And will Albert overcome his horror at the decadence around him, and learn to trust Victoria with his secrets?
