This is my interpretation to the lower layer of the movie: Batia, whose parents abandoned her when she was a child, abandoned herself too within all the stress and loneliness of life in the big city. The sea shore is the place in which Batia is reconnecting with herself. The small child coming out of the sea symbolizes "Batia the child". Batia goes out for a journey of self search after this small child (herself). At the end, she finds herself, leave the small child at the bottom of the sea and reborn from the water to a new life.
Other characters in the movie have their own parallel plot lines of trying to survive in the loneliness and alienation of the big city. They seek love but the people around them rarely notice their existence. The different characters briefly cross each other in different points during the movie, but the alienation breaks only at the end of the movie.
After I saw the movie, I felt there is a lesson to it – not to abandon ourselves just because others abandoned us, reach to other people around us.
