Charming 60-something José (Josef Abrhám) returns to Prague after 30 years living in Mexico, though he was convinced that he would never see his hometown again. He was persuaded by his deeply-religious Mexican wife Dolores (Dolores Heredia), who is convinced that only a miracle that might be fulfilled by Prague's famous Infant Jesus can help their daughter Penelopé (Aislinn Derbez) get pregnant, and the ideal time for this is Christmas.

It becomes evident that the Infant Jesus is not the only one capable of making miracles come true in Prague. Penelopé's longed-for conception is definitely not the only one.
