A brief anti-conventional and intense love story built as a long conversation break in fragments over a 36-hour long period between a Japanese architect referred to as Him and a French actress, referred to as Her. They have had a brief relationship and are now separating. The two debate memory and forgetfulness as She prepares to depart, comparing failed relationships with the bombing of Hiroshima. Experimental, with a beautiful cinematography, it was nominated for an Academy Award for Best Screenplay and at the Cannes Film Festival. He was honored by both Italian and New York critics.
