Read the complete plot summary and ending explained for Up the Front (1972). From turning points to emotional moments, uncover what really happened and why it matters.
During the First World War, Lurk, [Frankie Howerd], a lowly servant in the household of Lord William Mervyn and Lady Linda Gray Twithampton, is hypnotised by The Great Vincento, [Stanley Holloway], and travels to the Western Front to “save England.” Lurk is inspired to bravery, and upon receiving the German master plan for the entire war, which has through an unlikely series of events been tattooed onto his posterior, he becomes a hidden beacon of courage, pursued across France by German intelligence.
After breaking into the British military headquarters to deliver the plans into the hands of General Burke, he is confronted by Mata Hari, [Zsa Zsa Gabor]. In a dizzying turn of events, Mata Hari’s schemes are foiled, and a comic confrontation ensues as Lurk is drawn into a perilous chase. A wild chase scene unfolds in which he is pursued by the nefarious Von Gutz, [Lance Percival], and his henchmen Donner and Blitzen, weaving between corridors and stairwells in a blend of slapstick and suspense. The action swirls around the Allied headquarters as Lurk navigates a series of dizzying escapades, including a lively Can-Can performed by the Famous Buttercup Girls, a spectacle that heightens the chaos and laughter while keeping the mission in sharp focus.
Gradually, the stakes tighten as Lurk, aided by luck and wit, makes a daring move that culminates in presenting the plans to General Burke, though not before a moment of levity and danger that tests his nerve. The moment of triumph arrives when the mission is completed and the information is safely delivered into the hands of British intelligence, securing a medal of honour and a promotion for Lurk, a recognition that seals his transformation from a humble servant to a folk-hero figure.
With the war plan secured, Lurk turns his attention to personal happiness, winning the love of his beloved Fanny, [Madeline Smith], and fending off the wicked Sgt. Major Groping, [Bill Fraser], whose scheming had threatened the mission from the start. This unlikely tale blends humor, theatrical bravado, and wartime intrigue, tracing Lurk’s improbable ascent from subservient duty to courageous action, as he threads through deception, espionage, and romance to emerge as a decorated ally of Britain.

In the chaotic days of the First World War, Lurk, a humble servant in an aristocratic household, faces a dilemma entirely his own making. While others march toward glory with patriotic fervor, Lurk has dedicated himself to the art of avoidance, dodging military service with every ounce of ingenuity his timid soul can muster. The household routine offers him a comfortable hiding place—a world of polished silver and hushed corridors—until an unexpected intervention forces him onto a path he never would have chosen for himself.
Enter The Great Vincento, a hypnotist whose theatrical flair matches his mysterious ambitions. Through a session that blurs the line between science and showmanship, Lurk finds himself transformed—or at least, thoroughly convinced—into something far braver than his nature ever intended. Dispatched to the Western Front, he steps into a theater of war that seems tailor-made to test his newfound courage, surrounded by military bureaucracy, colorful characters, and situations far beyond his accustomed station.
What follows is a wartime caper brimming with cheeky humor and irreverent wit, where Lurk crosses paths with glamorous spies and finds himself burdened with an extraordinary responsibility: the German master plan for the entire war, tattooed in a most unexpected location. As pursuers close in and absurdities mount, he must navigate a landscape where danger and comedy walk hand in hand. The film serves as a fitting close to Frankie Howerd’s beloved Up… series, delivering a blend of slapstick, theatrical bravado, and sharp one-liners that celebrate the unlikely hero in everyone.
