The Nostalgia of the Lemon Tree. Concha is Andalusian and emigrated to Catalonia in the 1960s. Her daughter, Paz, has just divorced and is in financial and emotional ruin, which is why she decides to return to the old family house in Barcelona, ​​a place and a city which she had left never to return. Since adolescence, Paz's obsession has been to leave behind her past as a daughter of immigrants, tired of being "the Catalan" during summers in the village near Seville where they come from and "the Andalusian" the rest of the year in the middle-class neighborhood of her parents.

Paz returns to Barcelona with many open issues and a bitter sense of failure and stagnation that coincides with the social and political crisis of the moment. Paz has never known the details of her mother’s story, Concha, a woman full of energy and passion who has managed to deal with life’s setbacks: the disappointment of her marriage after a whirlwind courtship, the terrible floods of Catalonia in 1962 of which she was a victim, the harshness of the first years of immigration, the impossibility of personal fulfilment through a love story later in life, and the growing distance away from her only daughter, through which she projects all her illusions.
