In wry long takes and glossy black-and-white, Laila Pakalnina's Latvian satire sharpens its knives on cold war boundary-watching with devastating wit. While three soldiers search for a border jumper who, Cinderella-style, has left behind only a single shoe, the camera tracks impassively as their antics become increasingly desperate. A study in juxtaposition and control, seems slight at first, but it slowly penetrates, as the simplicity of its construction raises its story to allegorical heights.
