A car accident separates two lovers. Yvonne knows her husband is dead. She signs for the body. But she has the feeling something has gone wrong. Valery lives when she sleeps, half a life in the shadows of hers, just as aware that the universe has taken a left turn. Meanwhile, Yvonne's brother, Isaac Asimov's biggest fan, is trapped between two worlds - and in his own madness. As the future approaches, everyone moves towards one event: the future causing their pasts.
