Christmas is the celebration of children and Thanasis intends to celebrate it exhaustively.

He will write a letter to Santa Claus, warning him of the consequences he will face if he does not fulfill his responsibilities, he will discover where his mom hides the cookies so he doesn't eat them all by himself and he will eat them all by himself, he will deal with the Christmas tree and sing carols with his friend Haris with great success, despite the joint problems they both have. However, the most important thing is that he will play the role of a shepherd in the school play, with Sissy as the Virgin Mary.

He will triumph there, but only after going through a Golgotha of artistic and emotional difficulties.
