The film "Julieta" follows Julieta Arcos (Emma Suárez) as she navigates 30 years of her life, from a nostalgic 1985 to a desperate 2015. As an older Julieta struggles with depression and loneliness, her younger self (Adriana Ugarte) recounts her experiences of love, friendship, and motherhood. Through a series of fragmented flashbacks, including the story of her relationship with Xoan Feijóo (Daniel Grao), and her estrangement from her daughter Antía, Julieta grapples with guilt, memory, and the consequences of past choices.
