The incredibly rich writer Sissy Goforth lives alone with her servants and nurses on the top of a Mediterranean island, on which she makes her own rules. Her days consist of dictating her autobiography and begging for injections. Here comes Chris Flanders, a.k.a. the angel of death - he has the weird habit of paying visit to unfortunate ladies shortly before their death. Sissy dresses him like a Japanese warrior, and he contemplates in that outfit the waves breaking against the rocks below. The witch of Capri - a neighbour - is invited to share their dinner, a larger than life - and still moving - monster of the sea.
