Lucja and Marina are two young females who attempt to run 500 km in 5 days in a self-organised challenge. While pushing their bodies to the limits they constantly fight with pain balancing between endurance and reaching the breaking point. Neither of them had ever run such a long distance before. Organisation and planning are crucial to make it successful, but not everything goes as it had been planned. Would they manage to accomplish their 500 km in 5 days challenge?
