The secret language of flowers, a forbidden love that blooms in secrecy, and a revolution that will change everything ...
Berlin, 1848: In a place where the Boxhagener Square will be built later, there are vast fields of fragrant hyacinths as far as the eye can see. These fields belong to the five Sunday sisters. They used to be very close, but a dark secret has come between them since their brother Heinrich's death. The middle sister, Alba, suffers a lot from this big quarrel, especially since her family is about to sell the fields that she loves deeply. Alba tries to make peace with her sisters and fight to keep Boxhagen alive using the language of flowers that her mother taught her. But one morning, a stranger lies in her flowerbed, claiming to be the new gardener. She falls in love with him head over heels, without knowing that he is a revolutionary planning an uprising. Their love changes how Alba sees the world, and she gains the courage not only to fight for a better future but also to confront her family's dark past.
