In an isolated Orthodox convent in Romania, Alina has just been reunited with Voichita after spending several years in Germany. The two young women have supported and loved each other since meeting as children in an orphanage. Alina wants Voichita to leave and return with her to Germany, but Voichita has found refuge in faith and a family in the nuns and their priest, and refuses. Alina cannot understand her friend's choice.
In her attempt to win back Voichita's affection, she challenges the priest. She is taken to hospital and the people of the monastery start to suspect that she is possessed. When the doctors send her back, Alina is included in the monastic routine in the hope that she will find peace. But her condition worsens and they finally have to tie her to a wooden plank to prevent her from hurting herself.
After ruling out all other options, the priest and nuns decide to read her prayers to deliver those possessed by the Evil One. They perform an exorcism, but the result is not what they had hoped, and Voichita begins to doubt the religious choice she has made. She decides to free Alina - but her decision comes too late. Inspired by the non-fiction novels of Tatiana Niculescu Bran.
