Sylwia Zajac is a popular 30-year-old fitness coach and influencer in Warsaw. She works hard to keep her body in shape, inspiring her hundreds of thousands of followers on social media. Sylwia loves all the attention, but despite the admiration of her fans, she is mainly looking for intimacy. When an Instagram post goes viral in which she talks about her loneliness, the outside world is shocked. Her personal message is inconsistent with her positive image and what the sponsors want to see. While the media discusses Sylwia's well-being, all the attention attracts a stalker. When she meets him in front of her house at night, she asks a friend to solve the problem for her. The consequences are drastic.
Sweat is a contemporary film about intimacy and loneliness in the age of social media from Swedish director Magnus von Horn (The Here After), who currently lives and works in Warsaw. The Polish theater actress Magdalena Koleśnik plays Sylwia in her first leading role in a feature film.
