It is part of a long term series of films about Mekas Jonas in the Desert 1991, Jonas at the Ocean 2004. The earlier films were focused more on Mekas work, while this film is more about the life of the legend of film avantgarde as he enters his 90s, still working, and still maintaining relevance in the modern world.
