Jim Belushi is Sergeant Joe Gunn, a tough American tank commander battling the Nazis in this remake of the classic Humphrey Bogart war drama of 1943. It is October 1942 and Sgt. Gunn and his two soldiers, Waco (Paul Empson) and Doyle (Mark Lee), are American tankers assigned to the British Army. When the Germans attack their positions, Gunn's tank is forced to retreat south into the Sahara. Desperately searching for water, they pick up a group of stragglers who lead them to the ruins of a Muslim shrine where they find the water they've been seeking. However, it isn't long before Gunn learns that a German detachment is also in the area searching for water. Though outnumbered, Gunn decides to stay and fight the Germans, hoping that British reinforcements will arrive in time.
