Only four days until Christmas Eve. The Gregorian family is caught up in pre-Christmas chaos: Mira (8) is whining from morning till night because she fears she won't get a pet for Christmas again. Selina (11) is constantly coming up with new plans to convince their relatives to give her money instead of a wool sweater this time. Mama Elli would love to involve the girls in her Christstollen baking frenzy. Then the newspaper announcement comes just in time: Donkey from the live nativity scene missing, reward offered by the mill courtyard! For once, the sisters are in agreement: They must find the Christmas donkey!.
