At the behest of their teacher, fourth grade schoolchildren in a small Croatian village found an old-style Slavic Zadruga and organize a field trip to Zagreb.
The scenes in Zagreb were taken at the Main train station, the Funicular, the Dolac Market, the National Theatre, the Zoo and a printing press.
The scenes in the school were shot in the village of Tomaš near Bjelovar, and the scenes in the snow near Grginac on the railroad between Bjelovar and Kloštar Podravski, with snow-blowers from Planica in Slovenia to provide artificial snow.
A replica of the train from the film has been installed at the Lovrak center in Veliki Grđevac.
The theme song "Kad se male ruke slože" ("When little hands join together"), written by popular singer Arsen Dedić, is a tale of friendship and solidarity.
