Louis Trebor, a robust and mysterious loner, lives alone in an isolated woodland compound on the French-Swiss border in the Jura mountains. An enigmatic figure and emotionally distant father, he has little contact with his grown up son, Sidney--who lives near Geneva with his wife, a Swiss border guard, and young family--seemingly preferring the company of his dogs. Trebor’s emotional contact is seemingly limited to an affair with a local pharmacist and a wordless attraction to a beautiful and equally aloof dog breeder. An ailing heart forces Trebor to leave his snow-covered wilderness to visit a bank vault in Geneva in order to withdraw enough cash for a new heart on the black market. Shadowed by a mysterious, unnamed Russian woman, Trebor recovers from a clandestine transplant operation, and travels to the bustling markets and shipyards of Pusan in Korea. Here he agrees to buy a boat and starts on a voyage south, slowly threading his way back to his former home on a remote island near Tahiti, where he searches for the lost son he fathered years before. He is uncertain of the welcome he will receive after all these years.
