Vis Invicta gymnasts arrive at the Winter Fox tournament. Martina should not have been there and her companions, like her fear, do not take long to remind him. Immersed in an icy and tense climate, the team trains to win.

The first day of competition, which Martina watches from the bench due to Rachele's decision, ends with a disappointing result and an uncontrollable anger from Carla, who drags her teammates into a challenge with the Romanian athletes.

The tension for the individual competition puts a strain on all the athletes, especially Martina. During an evening at the pub, a fight breaks out between the girls that worries Rachele, who confides in Alex about her, revealing her fears.

When one of the girls is found upset and bloody in the woods, Martina tells to Rachele what she knows, going against an oath she made with her companions. This betrayal, however, does not go unpunished for long.

On the morning of the final, Martina seems to have regained her determination and the Italians shine. But it is becoming increasingly clear that something is happening to the athletes.
