In the twilight of World War II, Captain Jack Wosick is a discredited army officer given an opportunity for redemption. Tasked with leading a unit of misfit soldiers known as the War Pigs, Jack must train and prepare them for a secret mission behind enemy lines. The team, made up of outcasts and oddballs, faces skepticism and ridicule from the military establishment, which doubts their efficacy and worth. To assist Jack, the army assigns a seasoned German-born French Legionnaire, Captain Hans Picault, who becomes both a mentor and a skeptic of the operation's success. Together, they must whip the War Pigs into shape, turning a rabble of undisciplined men into a coherent fighting force.

The unit embarks on their covert operation, aiming to uncover and extract vital intelligence about the Nazis' new super weapon. Facing harsh opposition and the dangers of the frontline, they must rely on each other's unique skills and grit to navigate through enemy territory. As their mission intensifies, bonds form among the men, with their individual stories of redemption and courage coming to the fore. The War Pigs push through the challenge, knowing that the information they seek could turn the tide of the war—but at a potentially great personal cost.
