5th April 1941, somewhere in Serbia. Several passengers take the Krstić & Son bus to Belgrade: A consumptive, a wannabe singer, a Germanophile who may or may not be a spy, a hunter, a veteran of the first world war, two Gypsy musicians and a newly-wed couple. The trip turns out to be rather eventful: While on their way, they encounter an army road block, a farmer who has ploughed the road as if it was a field, a funeral, a lack of suitable bridges, an army detail and more, only to arrive in Belgrade in the morning of the 6th of April...
Who's singing' over there (Ko to tamo peva/Ко то тамо пева in Serbian) is a famous 1980's Yugoslavian comedy about the bus trip described above. It plays out as a road movie, taking hints from Stage Coach and similar movies.
- The Alledged Bus: The bus is not exactly the most trustworthy vehicle - it's already obviously beat up at the start of the movie, and over time, it loses one tire and gets a hole in the roof courtesy of the Hunter.
- Artistic License Gun Safety: The Hunter shows surprisingly little concern over taking a loaded rifle onto a bus. Late in the movie, that earns the bus a new hole in the root, and the hunter a long walk to his destination.
- Badass Driver: Miko Krstić can drive the bus backwards while blindfolded for several hundred meters, and apparently, he does this a lot.
- The Casanova: The singer constantly flirts with the bride, and offers her to stay with him towards the end of the movie. The husband apparently doesn't notice.
- Downer Ending: The movie ends on the 6th of May 1941 in Belgrade. Coincidentially, this is the date when the Luftwaffe bombed Belgrade during the invasion of Yugoslavia during World War 2. Of course, the bus is caught in the attack, and only the Gypsy musicians survive.
- Greek Chorus: The Gypsy musicians, quite literally: Several times throughout the movie, the two of them break into a sad song about the state of the world, commenting the events of the movie so far.
- Only Known by Their Nickname: Most characters are only known by their description (the Singer, the Hunter, the Bride et cetera). Not very surprising, since they all meet on a bus and don't known each other.
- Road Trip Plot: The plot can be summarized as "People take a bus to Belgrade. Stuff happens".
