The Vis Invicta gymnasts arrive at the Winter Fox tournament. Martina, however, was not supposed to be here and her teammates, as well as her fear, will soon remind her of that. Immersed in an icy and tense climate, the team trains to win.

The first day of competition, which Martina, in line with Rachele's decision, watches from the bench, ends with a disappointing result and uncontrollable anger for Carla, who drags her teammates into a night-time challenge with the Romanian gymnasts.

The tension of 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 and Rachele, worried, opens up with Alex and reveals her fears to him.

When one of the girls is found distraught and covered in blood in the woods, Martina tells Rachele what she knows, breaking an oath made with her teammates. This betrayal, however, does not go unpunished for long.

On the morning of the team final, Martina seems to have found her determination and the Italians shine. But it is becoming increasingly clear that something is wrong with the gymnasts. After talking with Angelica, Martina's suspicions increase.

On the morning of the final, the girls face a terrible discovery: under a snowdrift there is a corpse. A series of confessions mix up the police investigation as the finding of the truth about the tournament draws closer and closer.
