Shortly before Christmas, 79-year-old Alfred Warner arrives at Berlin's busy central train station to meet his granddaughter Brynja for the first time. When she fails to arrive, Alfred, afraid and alone, is taken in by a stranger, Julia, who quickly realises that there is something remarkable about him.

Worried sick, Alfred discovers that his granddaughter is lying in a coma in a Berlin hospital following an unexplained accident and may take months to fully recover. After the sympathetic Julia insists he stays at her home for Christmas, Alfred becomes increasingly anxious and announces that his time is running out and that he has only six days left to live. He knows this because the voices he has been listening to for his entire life have told him so. Alfred insists he must tell Julia his life story in the hope of saving Brynja's life after he is gone. If Brynja does recover, she must finally learn the truth.

And so, over the ensuing six days he pours out his extraordinary tale. It has been a most uncommon life, but the one constant during each stage of his journey are the voices which accompany him, voices which for other members of his family, including Brynja, have been far less benign. Now Alfred's final duty is to make sure that Julia understands, so that Brynja does not become yet another family tragedy.
