Sammy Rice is a British scientist in a London ‘back room’ team evaluating new weapons during the Second World War, a setting where progress is constantly hampered by bureaucracy and poor management.
Rice is disabled and in constant pain from his prosthetic foot, and he nurses a brittle self-pity that makes him doubt his worth to his girlfriend, Susan. A secretary in his department, she tolerates his temper and self-destructive streak in the hope that she can help him move past his woes, though staying away from whisky is key to keeping him on track.
Rice, who has a past background in bomb disposal, is drawn by Captain Stuart into a hush-hush assignment that probes the secrets of a new Nazi booby trap device. Progress is slow, bogged down by internal snags and the ever-shifting political climate of the section.
In the midst of this turmoil, Susan urges him to be more assertive at his job, a demand that lands heavy on him and sparks tension between them. He lashes out in a drunken rampage, smashing up his flat, and she leaves him to face the consequences alone.
Still under the influence, Rice receives a call informing him that two intact devices have been discovered on Britain’s Channel coast. On his arrival, he learns that Stuart has died while attempting to defuse the first device. Before tackling the second, Rice listens to a transcript of Stuart’s remarks from the disarming process, and in a gripping, harrowing moment he discovers that the device has two booby traps. He disarms both, a feat that restores his self-belief and his professional standing.
Rice returns to London with his reputation renewed and his confidence restored. Susan guides him toward an urgent meeting with Colonel Strang, the army officer he had previously backed during a heated dispute over an experimental artillery gun. The colonel’s stance had opposed the project, and yet the meeting culminates in Rice being offered the chance to head the Army’s own new scientific research unit, with a commission as a major. He accepts, embracing a new chapter in his life.
Back in his flat, the damage from his earlier stormy night has been repaired, and Susan awaits him, signaling a hopeful new balance between them as the story closes.

Discover the spoiler-free summary of The Small Back Room (1949). Get a concise overview without any spoilers.
In the waning days of World II, the British war effort is as much a battle of ideas as it is of armies. Deep beneath the soot‑caked streets of London, a cramped “back‑room” of scientists, engineers and military officials wrestles with the relentless churn of bureaucracy while trying to keep the country one step ahead of a terrifying new German weapon. The city itself hums with an uneasy mix of resilience and dread, its civilians oblivious to the invisible menace that could turn ordinary neighborhoods into disaster zones at any moment.
Sammy Rice is the enclave’s reluctant hero—a bomb‑disposal specialist whose precise skill is shadowed by a lingering injury and a phantom of past failures. His prosthetic foot reminds him constantly of the price of war, and a brittle self‑pity fuels a volatile temperament that threatens both his work and his love life. Susan, his steadfast girlfriend and department secretary, is the only voice urging him toward steadier ground, insisting that sobriety might be the key to reclaiming his confidence. Their uneasy partnership underscores a larger theme: the battle between personal demons and the collective fight for survival.
When a covert directive lands on his desk, Sammy is thrust into a desperate race against time to neutralize the mysterious, booby‑trapped device that the Nazis are dropping along the English coast. The assignment is cloaked in secrecy, its success hinging not only on technical brilliance but also on the fragile resolve of a man teetering on the edge of his own limits. Amid the ticking clocks of war and the oppressive weight of bureaucracy, the film unfolds as a tense, atmospheric study of courage under fire, where every whispered conversation and strained breath hints at a larger, unseen showdown.
