The protagonist is the lonely 40-year-old Petr, who works as an immigration officer in London. He returns to Prague when a woman, who dies in hospital after a car accident, calls him the father of her eight-year-old daughter Ema. Although the man has doubts about fatherhood, he takes the girls and lives with her in a hotel in the center of Prague before Christmas, where he meets the hotel manager Maria. In order to keep Ema, he decides on a fake wedding with her, even though he knows all the pitfalls of this plan and even though he has to face a commission officer from the childcare department. The initially withdrawn taciturn man gradually becomes closer to both "women of his future life" and them to him. It doesn't go without various setbacks, but miracles usually happen at Christmas.
