Maca (Mara Valverde), 30 years old and clumsy by nature, makes the most of life and strives to be happy. Maca's talent is wasted working as an assistant for an oppressive and terrifying fashion influencer and she spends her time with guys with whom she never manages to establish an emotional bond. Together with Jimena (Elsabet Casanovas) and Adriana (Susana Abaita), her two unique and lovable friends who are always ready to do whatever it takes to make their problems not seem so bad, Maca has managed to make Madrid a city where everything is possible. Everything seems to be going well until he-who-must-not-be-named comes back into her life. Leo (Alex Gonzlez), the love and biggest mistake of her life, the man who tore her heart apart, obliterated her self-esteem and her faith in men, comes back into her life to turn everything upside down. Maca has tried to forget him, but now she has to accept that he has returned and face the emotions she has locked away to deal with the unforgettable memory of what could have been and never was. Old wounds are reopened and Maca will have to be brave and confront her conflicts, fears and insecurities in order to finally take control of her life.
