Two couples. The four characters are played by eight actors. There is little dialogue. Sometimes a couple does not seem to live together, just to be alive together in the same room. Each one of them at one time walks through an anymous part of Amsterdam. They put their feet down with a will, clicking their way through town. We do not know where or why they are going. To a meeting, to get some exercise, nowhere? They have difficulty in communicating. They leave notes to each other on the table rather than talk.
