Plot summary

In Paris, Lucas works as a computer scientist and has just devised a new computer language when he learns he has a rare and fatal brain disorder. It will strip him of his memory and leave him unable to speak clearly. Leaving the hospital, he goes into a café, where a young woman named Blanche catches his attention. She walks out soon after he orders dinner for them both, and he stays in the street until morning. She drives past, stops and weeps, then goes on to work. Her job is at a hotel in Biarritz, where her clairvoyant act has her take off her clothes. Lucas follows her to the resort.
