Paris, today. The Museum of Broken Promises is a place of wonder and sadness, hope and loss. Every object in the museum has been donated - a cake tin, a wedding veil, a baby's shoe. And each represent a moment of grief or terrible betrayal. The museum is a place where people come to speak to the ghosts of the past and, sometimes, to lay them to rest. Laure, the owner and curator, has also hidden artefacts from her own painful youth amongst the objects on display.
Prague, 1985. Recovering from the sudden death of her father, Laure flees to Prague. But life behind the Iron Curtain is a complex thing: drab and grey yet charged with danger. Laure cannot begin to comprehend the dark, political currents that run beneath the surface of this communist city. Until, that is, she meets a young dissident musician. Her love for him will have terrible and unforeseen consequences.
It is only years later, having created the museum, that Laure can finally face up to her past and celebrate the passionate love which has directed her life.
