It is June 11th 1994 in the depths of Herefordshire and Natasha Devereux's family and two hundred guests gather together to celebrate the fiftieth anniversary of St Martins. From the vision of one woman who fled Bolshevik Russia and opened her doors to artists, musicians, writers, and refugees from war-torn Europe, it has become a sanctuary for generations of her family. Over the course of one day they face marital crisis, impending birth, teenage trauma, a father's roving eye, momentous news from the past, communal financial crisis, and a lost love from the summer of 1957.
