Red Meridian
Two enemy scouts cross a lethal salt frontier with the proof their war was manufactured.
Two enemy scouts are forced to cross a lethal salt desert with one passenger both armies want. The simple mission version is escort, survive, deliver. The better story is what happens when survival gives them enough time to hear each other instead of the propaganda that sent them there.

Concept frame 01
Two scouts cross a frontier where the landscape is less dangerous than the orders behind them.
The war is not treated as abstract spectacle. Ordinary people have been taught that the other side is the reason their families suffer, while the real decisions are made in rooms far away from the heat, hunger and bodies.
The film should stay tense and physical: water, light, ammunition, cracked maps, unreliable coordinates. The message only works if the scouts earn it through danger, not speeches.
