During a religious retreat with her friends, 17-year-old Ainara makes acquaintance with a mother prioress. Ainara's aunt, Maite (an atheist
cultural manager), takes Ainara home. Ainara asks her father Iñaki (a widower and
restaurant owner more interested in his business and his new girlfriend Estibaliz than his eldest daughter) about the possibility of spending more time with the nuns, while her friends are in a exchange program. While in Maite's apartment with Maite's partner Pablo (an applicant for a position as a teacher in the
Basque education system) and their son, Maite pumps Ainara for information about Ainara's intention to start a "vocational discernment" process and potentially become a
cloistered nun. Her aunt reacts with astonishment and advises her niece to experience more of life before making such a decision. After meetings with Ainara's "spiritual guide" Father Chema in the context of the State-subsidised religious education Ainara and her father and aunt before her have been raised, Ainara maintains her intention to continue with the spiritual process, claiming that she speaks to God and God sometimes answers her back. Ainara's grandmother María Dolores tells Ainara of the sadness that her absence would cause. Maite and Pablo's marriage is in crisis. Maite tries to persuade Ainara's friend Izaskun to try to broaden Ainara's horizons and activities. She finds out that Ainara fooled around with Mikel, a fellow choir member. While sharing the same bed in a country house with her friends, Ainara feels attracted to Mikel. Eventually, while back from choir practice in Ainara's bedroom, Mikel kisses Ainara and they start
petting. They are discovered by Estíbaliz and Ainara's two younger sisters. This and Ainara's reaction in denial suggesting that Estíbaliz somewhat lied about the scene provoke Iñaki's anger and a family row at the dinner table. Maite and Iñaki visit the Mother Prioress and beg her to advise Ainara to be patient, and to allow her to study for a university degree. The Mother Prioress refuses to do so, leaving such matters in God's hands, while Maite explains to the Prioress that Ainara developed emotional issues after her mother died. Concerned about the costs, Iñaki refuses to send Ainara abroad even though he took a €310,000 loan for his restaurant. While on probation at the convent, Ainara bonds closer with a young nun. Ainara's probation is interrupted by María Dolores' death. After the funeral, Maite explodes with rage at Iñaki, reproaching him for leaving her without an inheritance from the half of María Dolores' home (which was used as
collateral for Iñaki's loans) and for not asking Ainara to stay, likewise suggesting that Iñaki let his daughter go because it is cheaper to look after two than three daughters. She also derides the nuns and dramatically pleads Ainara not to be fooled by them. Ainara replies that she will pray for her. Maite takes legal action to disinherit her brother and her eldest niece. Ainara
takes the vows, becomes a cloistered nun, and Maite faces challenges ahead. == Cast ==
