Lyuba is a woman who is heading for a weekend retreat with her friends, Sveta and Zoya. For Lyuba, it's a chance to escape her troubled home life. She has been in an abusive marriage with Sergey, who constantly finds excuses to belittle her and make her feel bad. Despite feeling uneasy about leaving home and attending the retreat, Lyuba is persuaded by Sveta and Zoya to join them. Although they arrive late, the group is warmly welcomed by the retreat's leader, Danila. Danila leads the participants through unusual rituals, such as dancing to release pent-up aggression. However, Lyuba begins to experience strange visions, which make her uneasy. She becomes intrigued by Danila, who, at one point, buries her up to her head as part of the retreat's activities. As Lyuba starts to feel more uncomfortable, she contemplates escaping the retreat. But she fears that what awaits her outside might be even worse than what she faces within.
