I think that I recognize the parent's allusion. The film is Ukraine on Fire, directed by Igor Lopatonok.

The executive producer (better known for his work as a director) was Oliver Stone. You can buy it on DVD from several major retailers or pay to get it instantly via streaming on Amazon Prime.

The reason "few US citizen seem to know about it" is probably because most US citizens don't watch political documentaries.

Thank you. I'd agree with that presumption. It should also be clear that events in Ukraine have definitely evolved since 2016. Reception seems to imply that multiple sources dismissed the film as Russian propaganda at the time as well. Of course I can't say that for myself without watching it, but I'm noting it as significant.
