Colonel Michael Donovan, Victor McLaglen is a battle-hardened soldier of fortune and a former U.S. Marine captain who has grown tired of babysitting the spoiled playboy George Foster in Paris. When revolutionaries Valdis and Ledgard recruit him to kidnap King Peter II, Freddie Bartholomew accepts the dangerous assignment. Donovan’s wary pragmatism clashes with Foster’s reckless bravado as the two men set out on a mission that promises danger, excitement, and a possible reshaping of a Balkan regime. Valdis is portrayed by Lumsden Hare and Ledgard by Walter Kingsford.
At a masquerade ball inside the king’s palace, the mood shifts from glitzy to tense as the would-be captors survey their target. Foster is quickly drawn to a captivating woman named Sonia, a presence whose charm masks deeper loyalties. Sonia, the Countess Sonia, is brought to vivid life by Gloria Stuart, adding a note of grace and danger to the unfolding drama. Donovan and Foster observe the palace corridors with careful eyes, while the mystery of the king’s presence lingers, heightening the moral dilemma: kidnap a boy-king or refuse a mission that may empower real reform.
When night falls again, the pair sneak back into the palace only to discover that the king is indeed a boy—an innocent faced with immense expectations. Donovan’s disgust grows, even as Peter’s eager curiosity for adventure brightens his expression. Peter greets the notion of danger with a child’s naïve thrill, thinking the two men are Chicago gangsters from the stories by Damon Runyon. The situation spirals when Countess Sonia stumbles upon the scene and raises the alarm, forcing a tense exit. A secret escape passage offers a glimmer of hope, and Sonia accompanies them, reluctantly joining in to safeguard the young ruler. The passionate, fate-filled sequence tightens as the trio flees toward uncertain safety.
Prearranged, Peter is taken to Lady Augusta, a figure revealed to be Peter’s former nurse. Lady Augusta, played by Constance Collier, embodies a trusted, maternal authority amid political upheaval, and her role foreshadows the fraught loyalties at play. Donovan’s employers—who aim to topple the boy-king’s government in favor of a reformist regime—succeed in overthrowing Gino, the hard-edged leader of the old order, and install Stefan Bernaldo, a reform-minded administrator, at the helm. Stefan Bernaldo is portrayed by Pedro de Cordoba, while Gino’s fate looms as a grim reminder that power is a volatile currency in these volatile lands. The betrayal and the upheaval set the stage for an uneasy alliance between Donovan and the new government as the drama deepens.
As time passes, Donovan grows genuinely fond of Peter, and the two develop a reciprocal respect that borders on mentorship. Donovan teaches the boy how to play baseball and even how to roll craps, seasoning their companionship with tall wartime tales that blur the line between memory and legend. Peter, in turn, offers Donovan a glimpse of innocence restored through responsibility. Meanwhile, Foster tries to win Sonia’s heart, presenting himself as a true suitor rather than a mere conspirator. Sonia, torn between duty and affection, attempts to navigate a precarious path, ultimately deciding that loyalty to Peter’s welfare supersedes romance. Sonia’s actions reveal the complicated web of loyalties that binds everyone involved.
In a tense turn, Edric—Prince Edric, a royal figure whose word carries weight in the shifting political landscape—begins to spread rumors that the reform government has killed the king. Edric’s alarm signals the fragility of the new balance and foreshadows the power plays that threaten the fragile peace. The gypsy camp becomes a conduit for crucial information, as Sonia transmits a vital message to Gino revealing Peter’s location. Gino’s men press forward, and Donovan and Foster must improvise a plan to outmaneuver their adversaries. The clock ticks as the rebels and their opponents close in, and every decision carries high stakes for Peter’s safety and the future of the country.
The final confrontation culminates in a dramatic, kinetic defense as Donovan wields a M1917 Browning machine gun to wide effect, turning the odds against Gino’s forces. He fights with grit and precise restraint, eliminating or capturing hundreds of adversaries just in time to prevent Peter from facing a firing squad. When Gino resists, Donovan makes a decisive end to the threat. In the aftermath, Peter expresses his gratitude with a formal decoration, a symbol of reconciliation and unity after a period of fear and upheaval. The two men share a tearful farewell, each aware that the bond forged under fire will endure in memory even as life moves forward.
