Everyone is suspiciously pale. Humankind of the future is beset with epidemics. Part of the planet is shrouded in eternal darkness. The world is divided by impassable borders. It’s not some second-rate dystopia but a spectacular game with the audience, with the narrative, with the genre. The picture connects the unconnectable as it unfolds a labyrinthine plotline in a single shot. For viewers drawn under its spell, the self-referential story is highly engaging for its knack of creating ever newer hypotheses. What was at first an innocently linear detective story playing out in a minimalist sci-fi setting expands in scope, and the reconstruction of a crime transforms into a tragic love story.
