Summer holidays. Rebellious Agata comes to a small town to work at a religious camp for teenagers and youngsters. 17-year-old Mirek bets he will seduce her, while his grandfather – who suffers from dementia – sees in her his long-gone lover. Mirek uses his grandfather to get closer to Agata. Agata represents the liberal millennial generation who confronts the old-fashioned, catholic, conservative values represented among others in her vegetarianism and quite open approach to sex. As Agata and Mirek explore their relationship, they uncover a carefully guarded family secret.
