A Christmas Tale (2008)

When Junon and her husband assemble their oddball clan - all seemingly suffering from some kind of psychological or social malady - for Christmas celebrations, it isn't long before old family tensions and rivalries boil over. With brother and sister Henri and Elizabeth at each other's throats, Junon announces that she is suffering from a rare genetic disease, and will need a bone marrow transplant from someone in the family - but will anyone be willing to give?
