The film is a biblical soap-opera whose action unfolds in the Californian desert.
Karen and Wes's marriage is crumbling apart - like a sandcastle.
Karen can't even make love to her husband any more - the sand has managed to get everywhere.
Harry, a tax collector, is a witness to this marriage falling apart.
As a civil servant he hears Wes confession. However he isn't able to help him.
The omnipotent eye of television glitters above the desert - that raw allegory of America where neither the white nor the black have it good.
If Samuel Beckett and Joan Collins had a romance, then their child would look like this film.
