On the 70th birthday of famous piano virtuoso Hannes Westhoff, a celebration is to take place at the patriarch's estate. For this occasion, his second wife Anne not only invited Westhoff's three sons Max, Fredrik and Gregor, but also their mother, Westhoff's ex-wife Renate. While Anne tries to maintain a friendly atmosphere, old conflicts resurface among the family. With tensions already high, things take a turn for the dramatic when son Max reveals shocking news.
