The future is no more, and eternity has begun. It's 1986 and a nuclear reactor has exploded in Chernobyl. Syvert returns home from military service to live with his mother and brother on the outskirts of a town in Southern Norway. One night, he dreams of his late father, and can't shake him from his mind. Searching through his father's belongings for clues and connections, he finds a cache of letters that lead to the Soviet Union. In present-day Russia, Alevtina is trying to balance work and family. She has always sought the answers to life's big questions, but is preoccupied with care of her young son. Her friend Vasilisa offers some nourishment: she is writing a book about an ancient feature of Russian culture, the belief in eternal life. Meantime, Alevtina is heading towards a meeting that will redraw the contours of her world.
