Christmas Eve. Last day at school. The Soccer Kids, like all children, dream of carefree holidays. However, their school principal has other plans. Making all arrangements secretly, he announces to them that he has agreed with the president of the Inter-School Championship to hold the first Christmas children's soccer tournament in Little Seville. With which teams? With the world-famous Real, Atletico, and Barcelona, and of course, with their own, Soto Alto, known only to the surrounding villages. All matches will be played under the watchful eye of the hawk, a set of cameras that record all phases in 3D. Unprecedented events for Little Seville. However, the Soccer Kids are anxious! They are forced to play in the tournament without having time to train and having lost all nine matches in the championship so far... In this confrontation with the giants, what events will undermine their courage? Will they manage to solve the mystery that is upsetting all of Little Seville? And in the end, which "great team" will win the tournament?
