In the waning days of World War II, a battle-hardened U.S. Army sergeant named Wardaddy commands a Sherman tank and its five-man crew on a deadly mission behind enemy lines. Outnumbered and outgunned, Wardaddy and his men face overwhelming odds in their heroic attempts to strike at the heart of Nazi Germany. The crew, hardened by the realities of war, share a strong bond forged in the fires of combat. However, the group dynamic becomes strained with the addition of a new assistant driver, Norman, a young and inexperienced soldier thrust into the harsh realities of war.

The crew initially mistrusts Norman due to his lack of combat experience and naivety. Throughout their arduous mission, they encounter brutal resistance from the German forces, with intense and unforgiving combat testing the limits of each man's courage and will to survive. As they move deeper into enemy territory, Norman’s innocence begins to fade, and he must come to terms with the necessary violence of war. Facing morally complex situations and the brutality of battle, the crew of the tank navigates through the harrowing European Theatre, their resolve and loyalty to each other their only support against the chaos surrounding them.
