Nath is, once again, exasperated by the guys. She has just been kicked off the men's hockey team that Marc and Laurent are on. With Aude, she decides to create her own women's ice hockey team and face the boys' team. They have a week to learn everything! The girls start recruiting a few friends and Aude enlists, almost by force, Thomas as Julia (still as motivated to play sports...). The beginnings are more than difficult and the training sessions are a real disaster, because the girls don't even know the rules, as for adjusting the equipment... we don't even talk about it... Fortunately for the girls' team, Thomas' paternal grandfather, Artémus, a colorful adventurer, who has arrived for the week, decides to take them under his wing... To lead them to victory and given the level of the girls, all tricks, even the most devious, are now allowed...
