In a green forest in Southern Estonia, women meet in a dark sauna. Here, enveloped in heat and smoke, they share personal stories. Intimate and painful narratives merge into a universal tale about self-acceptance, femininity, and the search for a partner. The Estonian smoke sauna is included in the list of UNESCO Intangible Cultural Heritage. The 'Sisters of the Sauna' acquaint viewers with sauna traditions while gently showing that vulnerability requires courage. The film was awarded Best Directing in the documentary category at the prestigious Sundance Film Festival. N-13 Film in Estonian with Lithuanian subtitles.
