Birta is 11 years old and the best handball player on the team. But her shoes are too small, and the team fee has not been paid, again. She lives with her little sister and her mother in Iceland. Her mom works around the clock at the hospital but struggles to keep their little family financially afloat. One day Birta overhears her mom on the phone saying that if she can't save up 100 000 Icelandic króna within a month, Christmas is ruined. Birta gets to work; she will earn the money for her mother and save Christmas once and for all!
