Inspired by 'The Prisoner of Zenda' by Anthony Hopes, 'God Save the Queen' retells the story, but with a twist.
The tiny Alpine kingdom of Schwarzburg Immenstadt is plunged into crisis following the death of its King and the secret abduction of the sole heir, Crown Princess Fredericka whilst she is returning from England where she had been a lady in waiting to Alexandra, Princess of Wales.
The King's lifelong friend, chief advisor and spymaster, Colonel Ernst von Hartmann, suspects Duke Michael, the Crown Princess' cousin is behind the abduction in a bid to seize the crown for himself. Desperate to play for time whilst he searches for the Crown Princess, he devises a royal deception, one involving a most unlikely hero, Lieutenant Rupert Woodson of Her Britannic Majesty's White Hussars, as brave and daring as he is unconventional.
In the wake of an unusual and desperate rescue mission on the Northwest Frontier Rupert, along with Sergeant William Bryce and Bugler Neil Hayes, find they have become heroes. Summoned home to be decorated by Queen Victoria, Rupert takes advantage of this opportunity to indulge his passion for mountaineering in the Alps where he comes face to face with Colonel von Hartmann who is stunned by the young officer's resemblance to Crown Princess Fredericka.
Colonel von Hartmann manages to convince an unsuspecting British government to offer him Rupert's services to play a role that he is uniquely qualified for, taking on the guise of Crown Princess Fredericka von Hoehental. Unwilling to abandon their officer, both Bryce and Hayes also manage to work their way into von Hartmann's deception.
Colonel von Hartmann's efforts are ably assisted by his severe and dutiful daughter Gabriela, who finds herself appalled by Rupert's capricious manner and irreverent humor. Only slowly does she come to appreciate his behavior is yet another disguise, one carefully crafted to hide a deeper secret that Rupert is desperately unwilling to face.
The sudden appearance of Rupert in Schwarzburg Immenstadt, where all believe he is the true Crown Princess, forces Duke Michael to resort to increasingly desperate measures in an effort to undo von Hartmann's counterplot. This eventually leads to him abducting Gabriela and results in yet another daring rescue by Lieutenant Woodson of the White Hussars.
