In a one-room ger in the Mongolian capital, Ulaanbaatar, lives lanky teenager Ulzii; his widowed, alcoholic mother; and his three siblings. His mother is unable to earn enough to feed all her children and it falls to Ulzii to supplement the family income by doing odd-jobs - unloading a van or delivering meat, for example. But he has a special, intuitive talent for physics, and an inspirational schoolteacher suggests he enter the national physics competition (yes, such things exist - introducing the film at the 2023 London Film Festival, editor Alexandra Strauss explained that although this film is a work of fiction, it is based on a documentary). If Ulzii wins, he will get a scholarship. But with all of his family responsibilities, can he put in the time required for study?
For Western audiences, a film from Mongolia is a rare treat. As well as the central plotline, the film also provides a look at modern Mongolia, where ancient traditions meld with today's way of life: in one scene Ulzii is sent to visit his aunt in her modern, high-rise flat in order to place his big toe in his infant nephew's mouth - this, apparently, is a sure-fire way to cure a facial rash. As the film progresses (writer/director Zoljargal Purevdash cleverly marking the passage of time by every so often changing Ulzii's hairstyle) we see Mongolian teenagers acting like teenagers anywhere: play-fighting, playing sports, lusting after a pair of stylish trainers.
The adventures of a physics student does not sound like a promising subject for a film and it is interesting to speculate whether this film would have worked if it were set in the UK or US; I suspect not. But set in a country that rarely features in Western entertainment, it works a treat.
