It is Christmas Eve. Janusz (Daniel Olbrychski), a taxicab driver, plays Santa Claus (roughly equivalent to Santa Claus) for his children and then comes home as himself (crossing paths briefly with Krzysztof from Dekalog: One) to his wife and children, in order to spend the evening with them. They attend Mass (liturgy) in the city. There he spots Ewa (Maria Pakulnis), with whom he had an affair three years earlier. Ewa just happened upon the church after visiting her senile aunt in the retirement home (the confused aunt asks Ewa whether she's done her homework, but also enquires after her husband).
