A documentary film about a unique sporting adventure in the heart of the Strážov Mountains. Ultra-runners Eva Mareková and Branislav Filo set out on a 100-mile loop in a self-sufficient style, relying only on themselves and the beauty of wild nature. The challenge tests both their physical endurance and mental resilience. Along the way, Eva manages to set the fastest known time (FKT) on this demanding route. The film is an authentic testimony to the power of friendship, determination, and the freedom of movement in the mountains.
