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. And when Ruda (Václav Postránecký), his friend from Prague, also insists, José agrees to return to the places he used to know and to the memories that they bring back--including his former Prague love Kveta (Libuse Safránková). 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.
Tragicomic family film about the world of children heroes - particularly the son of a local communist officer and his friend, a little hostage of the regime, whose parents emigrated to the West, few years before "Prague Spring" and the occupation of Czechoslovakia. Camaraderie, the first big discoveries of love, enemy gang fights and naive ideas are confronted with the reality of adult's world. The film is about the first contacts with bizarre and absurd reality of relationships and attitudes of adults, politics, emigration, but also betrayal and death and about how all those things form and transform the lives of small boys, who are forced to grow up too quickly.
