The sole plot of this boldly experimental film essentially sees its protagonists running for their lives: two young men escape from a train transporting wretched prisoners to a Nazi concentration camp. The boys are merely shown wandering through unfamiliar woodlands, captured in long shots or with a hand-held camera, which often assumes the perspective of one of the youngsters. The result is an impression that we are direct participants in their experience as hunted animals, heightened by fragments of unsettling scenes that drift between reality and delusion as their feverish imagination does its work. Instead of a linear narrative we have a loose associative chain of disparate plot details; the film gets by with virtually no dialogue, and the music is replaced with large swathes of silence.
