Middle-aged Paul (Mimi Branescu) frolics nude with his frisky young mistress (Maria Popistasu), then attends to the mundane chore of Christmas shopping with his wife (Mirela Oprisor). We sense a bomb ticking in Radu Montean’s devastating domestic drama even before husband, wife, little girl and mistress all end up in the same room; we know how destructive divorce will be for all concerned — and yet we can only watch as the inevitable looms. When it arrives, in an 11-minute unbroken take that mimics a slow swirl down a drain, it leaves only scorched earth — thanks to some of the most wounding, honest movie acting I’ve ever seen. If you’re thinking of cheating, see this movie, one of the recent triumphs of Romania’s burgeoning national cinema — and get slapped, hard. In Romanian with subtitles, the movie screens free to the public as part of Sarratt’s International Lens screening series.
