Synopsis:

As with so many of Davis' films, this portrait of an ex-Vietnam vet turned hobo is a personal one. The man, who calls himself Beargrease, hops the railways from North Dakota through the Rockies to the Pacific rim, on a bitter, cold, hard track known as the Highline.

With a sound track that includes songs by Woody Guthrie and Bob Dylan, the film documents the daily life of this fiercely independent man, whose personal philosophy is a mix of common sense and profound anger at the condition of modern America. His thoughts and stories, and those of the other 'boxcar philosophers' he meets along the way, throw up major questions about human nature, freedom and responsibility, and the thin thread on which our own reality hangs.
