In 1940, a freshly qualified pilot, Pilot Officer T. B. 'Septic' Baird John Gregson is tasked with delivering a replacement Hawker Hurricane to the bustling airfield of Pimpernel Squadron. Just as he touches down, a damaged Hurricane lands ahead of him, and Septic’s quick reflexes let him leapfrog the other aircraft, narrowly avoiding a collision. Yet he cannot slow in time and crashes his brand-new fighter into the garden of Squadron Leader Barry Clinton Cyril Raymond. The impact tears at the ligaments in Septic’s neck, a diagnosis he makes himself thanks to his brief medical studies before the war. The mishap instantly elevates the tension around the airfield, especially for the squadron’s leadership.
The following morning, Group Captain "Tiger" Small Jack Hawkins informs Septic that he won’t be able to fly until his neck heals, so Septic shifts to duties in the operations room. As days pass, a looming bombing raid puts the entire airfield at risk, and Small takes decisive action to protect the Hurricanes already stationed there. He orders a full scramble, pulling together every available pilot and turning out whatever aircraft can still fight. In a bold personal challenge, Septic races Small and wins the contest for the last spare Hurricane, seizing a chance to prove himself in the skies and to justify the unit’s hope in him. The moment is electric, but the victory is tempered by the larger mission at hand: Septic goes on to shoot down a Messerschmitt Bf 110 from the attacking force, a moment of triumph that quickly collides with discipline and caution.
Back on the ground, Septic’s elation is checked when he’s rebuked by Small and Squadron Leader Peter Moon Michael Denison for leaving his radio on transmit. That slip prevents the returning Hurricanes from getting warned to divert to an undamaged airfield, a misstep that tempers his celebration with a hard reminder of the responsibilities borne by every pilot. The reprimand nudges Septic back toward his ground duties, and the squadron carries on with its tense balance of risk and duty.
Time passes, and Septic fights his way back into operational duty, joining the Pimpernel team again. Yet the cost of war lingers: Septic is mortally wounded while pursuing another German aircraft, the combat taking a heavy toll on him despite his earlier bursts of speed and courage. His final words crackle over the Sector control tannoy, a stubborn note of resolve in the midst of loss: > Your message received and understood. Out
The scene closes with a quiet, haunting image: Nadine Clinton Dulcie Gray hanging an oil lamp in the ruins of her bungalow to guide returning pilots, a poignant reminder of the human cost that surrounds every flight and every mission.
In a blend of brisk action and earned sacrifice, the film traces Septic’s rapid rise, his early triumphs, and the heavy price paid when timing, duty, and fate collide in the chaos of war. The narrative keeps its focus on the men and women at the heart of Pimpernel Squadron, balancing moments of levity—like the spur-of-the-moment race for the last spare Hurricane—with the gravity of combat and the personal losses that shape their resolve.
