In Thin Air (2006)

A documentary film-maker comes to a film school in search of a legendary student leader. But instead of a revolutionary, he stumbles across a revolution in the making. The ingredients are all there but the circumstances are absurd. Both the warring parties seem to exist in a world of their own choosing. While one faction prefers to walk backwards, cover their heads and always talk on the phone; the other prefers to escape this 'reality' and sit on trees instead.
