In the hills of Valencia, a forgotten house guards its secrets. The whitewashed walls have crumbled, and the garden, laden with orange blossom, grows wild. Emma Temple is the first to unlock its doors in seventy years. Emma is London's leading perfumier, but her blessed life has taken a difficult turn. Her free-spirited mother, Liberty, who taught her the art of fragrance making, has just passed away. At the same time, Emma has separated from her long-time lover and business partner, Joe, whose baby she is carrying. While Joe is in New York trying to sell his majority share in their company, Emma decides to leave her job and travel to Valencia, to the house her mother mysteriously purchased just before her death. Emma makes it her mission to restore the place to its former glory. But for her aging grandmother, Freya, a British nurse who stayed in Valencia during Spain's devastating civil war, Emma's new home evokes memories of a terrible secret, a part of her family's past that until now has managed to stay hidden.
