In present-day China, two drifters run a murderous scam, luring unsuspecting marks into working alongside them down the coal mines. There they kill their prey, fake a cave-in, then collect hush-money from mine-owners terrified about being shut down. Shot guerrilla-style in China's bleakest provinces—and promptly banned by the country's authorities—former documentarist Li Yang's feature debut is a spare, stunning slice of naturalist noir.
