Grass Labyrinth

A drama about a young man who is searching for a particular song, or maybe his father, or maybe his true self? He encounters many figures and places, where there are many contrasts: his diligent mother versus a disturbed prostitute, an endless ocean versus an endless desert, a young boy versus a grown man, but also there are lots of balls (that resemble pregnancy stones, some with lots of string around them), a long red string that turns up everywhere (I assume this is a Biblical reference?) and many female, male and childlike figures that begin to haunt the boy/man.
