Essential Killing sold out

The beginning: at First it looks like an ordinary war movie. Soldiers in uniforms, helicopters, prisoners wearing orange overalls with a hood over their heads. Then an accident occurs and one of the men manages to escape. It is night, cold, there’s snow. The nameless Jihadi (fascinating part by Vincent Gallo) is both predator and prey; the entire movie he is on the run and will do anything to survive.
Why? The producer gives us no clue whatsoever. The only thing we can hold on to is that man in the snow in a claustrophobic scenery. Must see!
