In the golden city of Amsterdam, in 1705, Thea Brandt is turning eighteen, and she is ready to welcome adulthood with open arms. At the city's theatre, Walter, the love of her life, awaits her, but at home in the house on the Herengracht, all is not well - her father Otto and Aunt Nella argue endlessly, and the Brandt family are selling their furniture in order to eat. On Thea's birthday, also the day that her mother Marin died, the secrets from the past begin to overwhelm the present. Nella is desperate to save the family and maintain appearances, to find Thea a husband who will guarantee her future, and when they receive an invitation to Amsterdam's most exclusive ball, she is overjoyed - perhaps this will set their fortunes straight. And indeed, the ball does set things spinning: new figures enter their life, promising new futures. But their fates are still unclear.
