Louis Trebor, a man nearing 70, lives alone with dogs in the forest near the French-Swiss border. He has heart problems, seeks a transplant, and then goes in search of a son sired years before in Tahiti. Told elliptically, with few words, we see Louis as possibly heartless, ignoring a son who lives nearby who is himself an attentive father to two young children, one named for Louis. He leaves his bed one night - and his lover - to kill an intruder; he dreams, usually of violence. Will his body accept his heart? Will his son accept his offer?
