This is a short surreal film, probably inspired by stream of consciousness. I can't say this is for everyone, taking into account a number of different factors, despite its style and age.
The film illustrates what can only be described as the alcohol and heat-induced nightmare of a sun-bather, who is overwhelmed by phenomena occurring on the beach around him, namely naval carriers and aircraft.
Judging by the soundtrack, if you couldn't discern anything from the overt symbolism, one can concluded improvisation and is the driving force behind the film. Because of this method of story-telling, there is not much be said about the character except that he is borderline and anxious, and the plot leaves its viewer much the same way.
Overall I can't say I enjoyed this too much, its seems to be an attempt to explore consumerism and militarism, if anything. But I can appreciate the attempt.
