Four American employees of an oil company stumble upon a major petroleum reserve deep in the Sahara Desert, but their discovery quickly turns perilous. Despite being warned that they are entering territory where the local tribe strongly opposes outsiders, they proceed with their exploration. As they attempt to return to their headquarters, tragedy strikes when their plane crash-lands amid the endless dunes. With limited supplies—scarce water, food, no functioning radio, and no means to repair the aircraft—the group faces a slow and grim countdown to death, knowing rescue is unlikely.
During their desperate search for supplies and survival options, one of the crew members, Tab Hunter's character, spots an unusual flag attached to an antenna rising from the sands. Curious and hopeful, they dig through the sand and discover an abandoned German tank from World War II, along with the mummified remains of its crew. This relic is linked to the 10th Panzer Division, a formidable unit of the Wehrmacht during the war, and the tank bears the name "The Steel Lady." It’s clear that this tank has been lost in the desert for about ten years, out of water, fuel, and supplies, trapped in the dunes with no hope of rescue.
After burying the German soldiers, John Abbott's character, the radio operator, attempts to repair their own radio using parts scavenged from the tank. He manages to send an SOS, alerting the world that they are alive. Unfortunately, just as he is about to transmit their exact location, the transmitting tube burns out, leaving their position unknown. Despite this setback, they decide to try and make it out of the desert by using the remaining gasoline from the plane to get the tank running. This requires sacrificing some of their scarce water to cool the tank's radiator. Once operational, the group plans to drive over a hundred miles to reach a French Foreign Legion outpost, which they hope will provide rescue and aid.
As they traverse the barren desert landscape in their newly revived tank, one of the crew members, Rod Cameron's character, makes a shocking discovery inside a hidden storage bay of the tank—an assortment of precious jewels. Although he keeps this secret to himself, the greed begins to simmer beneath the surface amid their perilous journey. Their voyage takes a turn when they encounter a Bedouin oasis, where the local leaders recognize the tank and the jewels. It is revealed that the tank's crew during the war had stolen these treasures from a rival tribe, and now the Bedouins—who have their own claim to the jewels—offer to exchange horses and a cargo camel along with food and water in return for the tank, believing it might still contain the treasure.
The American team agrees to the exchange, but Richard Erdman's character, Monahan, and the others later find that Anthony Caruso's Bedouin leaders have discovered the jewels. During the night, Barlow—one of the crew—returns to the tank to retrieve the loot but accidentally drops a jewel on the floor. The Bedouins, noticing the shiny object, find it the next day and realize the Americans are aware of the treasure. They demand the return of the jewels. Unaware of Barlow's secret, Monahan and his companions attempt to deceive the Bedouins, but tension mounts.
This confrontation ignites a fierce fight, forcing the Americans to flee back to their tank, which they hastily drive away, narrowly escaping with their lives—but not without injuries. Frank Puglia's character wounds Larsen in the chaos, and Barlow sustains gunshot wounds. Their escape becomes even more complicated when the tank’s radiator is punctured, causing the water to leak out, and leaving the vehicle stranded in the desert. Trapped in a tense stand-off with their pursuers, the Americans fight to hold their ground behind the armor of the tank, defending themselves against continuous attacks from the hilltops.
With limited options, Larsen, played by Richard Erdman, shows remarkable resourcefulness by cannibalizing parts of the radio receiver to build a makeshift transmitter. In a desperate plea for help, they send out a distress signal, which is finally picked up by a rescue plane. As the plane lands amidst gunfire from the Bedouin attackers, the stranded Americans make a last stand, with Larsen and Evans rushing toward safety. Monahan, thinking Barlow is too wounded to escape, tries to help him but Barlow, in a final act of bravery and greed, pushes Monahan away and locks himself inside the tank, using the machine gun to cover the others as they make their escape.
The plane manages to rescue the remaining crew, who are flown to safety with the jewels stashed away. Monahan intends to return the treasure to its rightful owners in exchange for oil rights in the region—a plan that speaks to his sense of justice and hope for future peace. During the flight, the crew reflects on Barlow's complex character: a drunkard and a man driven by greed, yet ultimately a hero who fought valiantly and helped save the others. His sacrifice underscores the story’s themes of greed, loyalty, and resilience amid the harshest of environments, making "What's After the Movie" a gripping tale of survival, treasure, and human spirit in the unforgiving Sahara.
