The idea is simple: A married woman and a single man meet. They love, they argue, fists fly. A dog strays between town and country. The seasons pass. The man and woman meet again. The dog finds itself between them. The other is in one, the one is in the other and they are three. The former husband shatters everything. A second film begins: the same as the first, and yet not. From the human race we pass to metaphor. This ends in barking and a baby's cries. In the meantime, we will have seen people talking of the demise of the dollar, of truth in mathematics and of the death of a robin.
