In 1944, after facing relentless racism during their time in the Tuskegee training program, the brave 332d Fighter Group, a squadron of young African American USAAF fighter pilots, finally find themselves in combat in Italy. However, their aircraft, the Curtiss P-40 Warhawk, are worn-out and struggling. Frustration arises as they are assigned ground attack missions targeting trains and enemy transports, realizing that their chances of engaging the Luftwaffe in direct aerial combat are slim. This tight-knit group, led by Capt. Martin "Easy" Julian (Nate Parker), Lt. Joe "Lightning" Little (David Oyelowo), Ray "Ray Gun" Gannon (Tristan Wilds), and Samuel "Joker" George (Elijah Kelley), under the sharp guidance of Major Emanuel Stance ([Cuba Gooding, Jr.]) and Col. A.J. Bullard ([Terrence Howard]), must contend with a reluctant white military hierarchy that is resistant to acknowledge their capabilities as equals.
Conflict brews between best friends Easy and Lightning, each grappling with personal demons; Lightning, a hot-headed and impulsive pilot, often endangers himself and others, while Easy, struggling with alcoholism, battles feelings of inadequacy. After returning from a challenging mission, Lightning becomes enamored with a beautiful Italian woman, Sofia ([Daniela Ruah]), igniting a passionate relationship.
In a turning point, Major Stance secures an opportunity for the Tuskegee Airmen to "light up the board" as they are called upon to assist in the Allied landings at Anzio, Italy during Operation Shingle. Here, they engage in a fierce aerial duel against Messerschmitt Bf 109 fighters, led by a notorious German ace known as "Pretty Boy" ([Lars van Riesen]), marking their first victories over the enemy and destroying a crucial German airfield. However, during the chaos, Ray Gun suffers an injury that impairs his vision. Though weakened, Ray Gun pleads with Easy to allow him to continue flying, and eventually, Easy concedes.
In light of their remarkable performance, the USAAF Bomber Command approaches Bullard with a request to use the Tuskegee Airmen as escorts for the Boeing B-17 Flying Fortress bombers, due to high casualty rates among bomber crews. Bullard agrees, demanding that they be equipped with the new North American P-51 Mustang. The aircraft, adorned with bright red tails, earn the squadron the unofficial moniker, and Bullard emphasizes the need to prioritize the safety of the bombers over reckless pursuits of enemy fighters. Their debut escort mission witnesses astounding success, as they take down multiple Luftwaffe planes while ensuring the bombers remain unscathed. However, tragedy strikes when Ray Gun is shot down and captured, and Deke, another pilot, crash lands but barely survives.
Deke's injuries force him into discharge while Ray Gun is presumed dead. This drives Easy into a deeper spiral of alcoholism, laden with guilt for allowing Ray Gun to fly. In a bid to support his friend, Lightning promises to fly more responsibly on the condition that Easy stays sober.
As the journey unfolds, the perception of the Tuskegee Airmen begins to shift; they garner respect from the bomber crews, eventually gaining access to the "whites-only" officer's club. Meanwhile, Ray Gun is now a prisoner in a POW camp, but he becomes involved in an escape plan. In a brave act, Ray Gun sacrifices himself to allow others to break free, while the remaining prisoners manage to inform the 332nd of his heroic act.
Lightning eventually takes the plunge and proposes to Sofia, who, after some hesitation, agrees to marry him if he remains in Italy.
The Tuskegee Airmen are then chosen for a monumental mission: to escort the first American bombers targeting Berlin. Despite their P-51s having ample fuel for the journey, the squadron faces propaganda limitations and is requested to only escort for the initial leg. However, when the fighters designated to replace them fail to arrive, Easy makes a pivotal call to continue the escort. They encounter Pretty Boy, now commanding a flight of Messerschmitt Me 262 jet fighters, and despite being outclassed, they manage to score some victories. In a critical moment, Easy finds himself under attack from Pretty Boy but is saved when Lightning heroically intervenes, ultimately sacrificing himself in the process.
Upon discovering Lightning's death, Easy faces his demons head-on, finally confronting his addiction. At Lightning’s funeral, a surprising twist occurs when Ray Gun re-emerges, having survived his ordeals in captivity.
Ultimately, the extraordinary contributions of the Tuskegee Airmen lead to their recognition, earning them the Presidential Unit Citation in honor of their valor and achievements in the face of adversity.
