King Ralph

The entire Wyndham royal family is electrocuted during a rainstorm while a royal portrait is being taken outside Buckingham Palace. The sudden tragedy triggers a crisis of succession and a scramble to find a legitimate heir. Sir Cedric Willingham leads a nationwide search for any surviving royal blood.

With no clear successor, Cedric mobilizes resources to identify any living heirs. He directs an urgent search across the realm to find someone suitable to inherit the Crown and stabilize the nation.

Duncan Phipps informs Ralph of his royal heritage, revealing a family connection back to Constance and the first Duke of Warren. A ring proof seals the claim, confirming Ralph as the sole surviving heir.

Ralph is flown to London where Cedric begins a crash course on royal etiquette and duties. He is introduced to the constraints and expectations of monarchy, preparing for a life he never anticipated.

On his second day of adjustment, Ralph visits a strip club and meets Miranda, an aspiring designer. He dares her to date him if the press proves his royal claim, setting the stage for potential trouble.

Lord Percival Graves opposes an American on the throne and starts bribing to create a scandal. He manipulates Miranda to publicly stir up trouble for Ralph, testing the new heir's popularity.

Ralph sneaks out for a clandestine date in Hyde Park, ignoring warnings. The next day, Miranda returns Graves' money, but photographs of their liaison exist, threatening Ralph's image and readiness for monarchy.

To shield Ralph from scandal, Miranda ends their relationship and distances herself after the photos become public. The break strains Ralph's perception of the royal life and tests his resolve.

Despite his cultural missteps, Ralph wins favor with King Mulambon of Zambezi during a state visit. He builds a small but loyal following and earns grudging respect from foreign leaders.

A plan is arranged for Ralph to marry Princess Anna of Finland to preserve the royal bloodline and secure oil contracts in the Baltic. The union would also support UK jobs and economic interests.

During the Finnish royal visit, Miranda attends a ball as Graves' setup. Photos of her kiss with Ralph reach King Gustav, and Ralph's impromptu performance of 'Good Golly, Miss Molly' helps push Finland toward Japan for the contract.

Phipps reveals that Cedric himself is an heir, complicating the political landscape. The revelation broadens the pool of potential monarchs and signals ongoing dynastic tensions.

Ralph addresses Parliament, apologizes for his recent missteps, and exposes Graves's sabotage of his claim. He reveals a bold industrial plan with King Mulambon whereby Zambezi will purchase mining equipment and Britain will open three car engine plants, securing thousands of jobs. Graves is arrested for treason. Ralph abdicates in favor of Cedric, becomes the third Duke of Warren with a lucrative stipend and his own recording studio on his country estate, and Cedric warns that without children the crown could pass back to Ralph.

Ralph marries Miranda and they have a son, Ralph II. He fronts a singing group, the Dukettes, and performs a cover of Duke of Earl, marking a hopeful new chapter as the credits roll.
